Has this community been advertised to people on the smashbros subreddit who may be looking to make the switch? Might be a good idea to make a post there with a link to this community and instructions on how to join.
This graphic is a good intro to how Lemmy works and how to think about it.
If anyone wants to go ahead and cross-post to the reddit sub, that might help attract more users here.
I don’t think most people care as much about the API changes as we do… so it seems like these groups will stay small for now. :(
