1. What do you go by collectively? (a system name, a shared username, group pronouns... etc.)
Our system is named Various Artists, often shortened to VA for ease of writing (sometimes that shows up as VA System for clarity). Our catchall names are Modems, SiIva and Davey (sometimes combined into the shorthand DMS).
Most of us share the same accounts (introns, centralcanoncontinuum, shutup-playthehits / playthehits, etc...).
Collectively, we use they/them/theirs and xe/xem/xyrs pronouns, but are lenient (as in, any pronouns works also.)

2. How should people refer to you? (should people address individual members whenever possible, or would you rather be referred to collectively, etc)
Typically, we prefer you refer to the fronter(s) presenting at the time. When it comes to referring to our entire system, or referring to us in a way that's "unspecified," we'd prefer being referred to as a collective. If, for whatever reason, our plurality is not public to whatever space we're being referred to in, our catchall names are the way to go.

3. What terms do you prefer for referring to yourselves as individuals (headmate/alter/system member/...), or as a group (system/collective/household/...)? Is there any other terminology for yourselves or aspects of yours experience that you use and want people to know, or that you dislike and want people to avoid when talking about you?
For individuals, we prefer: headmate > headfolk / brainfolk > system / VA member > alter.
For the group, we prefer: system > multiplicity > collective.
We've started to get slightly "allergic" to overly clinical language (i.e., headmates as "parts," the "ANP" and "EP" divisions) used towards us, but it's fine in moderation.

4. Who in your system are people most likely to interact with? (names, pronouns, short Twitter-esque bios, etc)
Here's the kicker: there's no good answer to this question.
Our system works in a way that has a lot of moving parts, and the "frequent fronter" group changes depending on situation, environment, social circumstances, internal circumstances, or sometimes for no discernible reason at all. We don't technically have "hosts" either, or at least not in a traditional sense.
I'd assume this part is frustrating for people who are trying to get to know (or already know!) us. I'd say it's worth trying to nab our PluralSpace (https://pluralspace.app/), or play the long game by going with the flow until you have a better understanding of the individuals you see most of the time.

5. Will people be interacting with any child members? How should they treat them? Is there anything they should know when interacting with them?
Yes. The few that we have are a little more mature than their supposed "age," so treating them like most others is fine. They may specifically get upset over any sort of topic a kid would get distressed over, so please be mindful if you can.

6. Are there any system members who are nonverbal or otherwise have difficulty communicating? What should others expect when speaking with them (having other system members translate, can speak normally over text but will need accommodation over voice, etc)
Some members with frequent or constant trouble communicating usually have "🔇" denoted in their PluralKit display name, or may have it written somewhere on their PluralSpace page. Some of these folks may copy text over from an AAC app which may make longer lulls in the conversation and requires some patience. Others may speak in ways individualized to them, typically using less words and/or more pictures or emojis.
Our entire system is affected by speech disorganization, so some chatter from us may come out nonsensical or hard to follow, even if the headmate in question has no problems talking otherwise. Please extend patience here, we're trying our best!

7. What should people do if they don't know who's at front?
We usually have our fronting status on our Discord profile, our website's main page, and on PluralSpace. If all of these are blank / display as "none", just refer to us by our catchall names and collective pronouns.

8. Is it okay for people to ask if they can talk to someone who isn't at front at the moment?
Gently: we find this question a little rude. Besides that, we have a very difficult time voluntarily switching, so doing so would be a bit of a hassle. Instead, you can ask the currently fronting system member to relay your message instead!

9. If someone talks to one of you, will other system members be aware of the conversation? Will they be actively watching, or just able to remember it later?
Memory gaps make the answer to this question a little messy. Most likely: vague memory of it might remain later for other alters, but nobody is typically actively watching. If the conversation was spoken word, it might not register in other headmates' memory at all.

10. Adding onto the above - if multiple system members will be aware of a conversation, will they want to chime in? If someone wants to speak to a system member one-on-one, what expectations can they have and how should they communicate this (for example, it may not be possible to block everyone out but they can try to pay attention to something else and not interrupt)
One-on-one conversation is typically not a problem, as everyone in VA is typically respectful of one-another's privacy. If a system member is "backseating" on a conversation where they are allowed to do so, the currently speaking member might mention what they think or want to add.

11. How out are you? What should people do when talking to people who don't know you're plural? (do you have a "singletsona" name and pronouns they should use; can they talk about knowing someone who's plural in nonspecific terms, without naming you; etc)
We're generally out on most online spaces, but none IRL. When mentioning us specifically to someone who doesn't know we're plural or is *unfriendly about the concept of plurality*, refer to us by our catchall names and collective pronouns. If you're referring to us as someone you know who's plural, it's up to you to decide whether namedropping us is safe in that scenario.

12. Do you have any internal communication difficulties, memory issues, switch triggers, etc that others should be mindful of?
Internal communication is kind of hit-or-miss, memory issues are moderate but might be more severe for certain headmates, most introjects may front upon hearing discussion of their source & most headmates generally will come closer to front upon hearing discussion of themselves.

13. Your stance on being asked questions? (about personal experience, preference, plurality in general, etc)
We LOVE it. Seriously. Ask us questions. We have a lot to say about our personal experience and we're always looking for a listening ear. General plurality is fun to talk about as well, but we can never speak for every system that exists and a lot of questions can be answered with "well, it depends."
