Additionally, the admins should determine a policy for commandeering abandoned communities. I know some websites have a policy where if no staff log in in [x] weeks, any user is allowed to request moderation. Maybe I should make another post about that.
This in particular is an excellent example. The only staff member, @[email protected], made this community, made (and deleted) two posts, and apparently hasn't done anything else for 3 years. This is an important community to the site and deserves attention.
As it stands, the sidebar is useless. It could explain the difference between Lemmygrad and the Lemmy software, link to better communities for contacting the devs for feature requests, give advice for people asking questions, link to relevant chatrooms if any, that kind of stuff. This preventative assistance helps prevent the place getting filled with useless, redundant or off-topic questions.
