Perhaps after some amount of time having announced themselves over in !newcommunities@lemmy.world and !communitypromo@lemmy.ca, or…I don’t know if there are communities for instances (the fediverse communities, presumably?), but likewise for them?
The combination of a promotional space and discussion for helping grow communities/instances could help ensure there’s always some activity keeping this community visible to those seeking help.
The newcommunities one in particular didn’t take issue with it? That was part of why I was asking, as I didn’t think they would appreciate posts about existing communities, but if they don’t mind then I take it it’s a non-issue.
On the last part, it may not hurt to see if different AskLemmy communities would be up for including them in their sidebars, and maybe featured posts with pointers to Lemmyverse and !lemmy411@lemmy.ca if they don’t have them already.
