There’s an instance admin community that should be able to help out with technical issues !lemmy_admin
There’s a matrix groupchat with most of the big instance admins as members, but I don’t know a lot about it tbh. Also would recommend letting people know your subreddit is trying lemmy at !reddit , and there’s another specifically for people announcing new communities but sadly can’t recall the name at the moment
I haven’t had a look at your sidebar yet, but add rules for bots and the such as you wish - here the frequently seen ones are autotldr and pipedvideobot. There is also communitylinkfixer but I haven’t seen it in a while.
No idea of the best way to promote it on Reddit, aside from popping a link in your sidebar over there? May be worth checking out the reddit communities for the three major instances that have migrated most of their users from reddit - lemmy.one (PrivacyGuides), programming.dev (Programming), and lemmy.dbzer0.com (Piracy)
Thanks for that info, it very useful. I’ve been wondering about bots, we’d talked about writing one to cross-post the subreddit’s content to the fediverse site.
