Another option is to make another community on another instance and make a post here redirecting to it. At one point it was better to have at least one mod located on the same instance as the community but I think that's been worked out already?
I'd be happy to subscribe and contribute where I can to a StardewValley community on Lemm.ee if you want to make one. A while ago I tried to revive this community and it was still pretty quiet, sadly.
