Yep, definitely not new, but in the past I have seen people promote not-new communities that nonetheless are tiny and have not been posted here before so I figured it was okay. If you're concerned this sub is losing its purpose you might want to message the mod about changing the rules or something. I do not mind seeing old communities here but my opinion is not the only one that matters, and !communitypromo@lemmy.ca does exist even if it gets far less traffic.
