FYI, i see a lot of users joining, but not many people are actually subscribing to the communities. Subscribing to the communities you like will help them grow within the fediverse and be easier to discover!
Currently, we're set up so that only admins can create communities, but we could also be configured to allow anyone to create them. For the moment, we've opted to go this route while we're starting up, but we might revisit that decision later and change it. That said, i can create a community for you if you want, what do you want the /c/ name (like a /r/ for a sub on reddit) to be?
