Why not participate in the existing one instead of creating a new one? Even if it isn't active, it's got 268 subscribers already. Adding duplicate communities is just going to cause confusion and split the users.
You could ask to be added as a mod there, or if the current mod isn't active anymore, post in !support@lemmy.world and ask an admin to make you a mod.
So how does this work? Do people reply to the posts with the AMA, or do they make a separate post? And would the AMA post be in this community or in another one like !askmeanything@lemmy.ca?
edit: this was originally in reply to a now-deleted comment about some challenges in changing the nominee, which would be resolved if Biden stepped down.
Don't let your beans be dreams.
