Our moderation team was just expanded recently. I can ask an admin if you like (you can't be an admin, those are just Itch.io founders). But is it really such a good idea to force growth? Quality beats quantity when it comes to community interaction. It seems to me that people talk plenty on the main community forum, and that's not even counting the communities of various jams or games. Be active yourself, post good conversation starters and people will respond in kind.

Could we open a Facebook group? Because the rule of Facebook is "Only 10-30% of page follower will see a page post (not sure)". So that we have 13k+ followers but each post gets 10-20 reactions only. But a group post appears in all group members' newsfeed. And in a group developers can promote their own games. And there are millions of gamers on Facebook who don't know about itch.io.
So, can we open a Facebook group?
