The complexity you're referring to is one of the reasons I made this. So that instead of them having to go through the process of making a Community which is complex relative to creating something like a subreddit, I made one for them that I can just give to a mod if the find their way here. It's a long shot, but it doesn't hurt to try.
So you created this community? All they would have to do is individually sign up to Hive and join the group. Then you can just hand over the control to the mods. Nice.
