Well creating a new community on a separate instance whould be a good plan B. For the purposes of making it easy to find for new users and not having dozens of dead communities with the same name it makes more sense to me to just use the one that exist. It would also provide a corner stone of users and post. That is unless somone else already made another community for this elsewhere but nothing came up in my searches for it.

From my understanding based on other post on here this is somthing that can be done by the instance mods. If I ask nicely enough.
