I created two communities. I am the only mod on them. The communities are incredibly small. I would like to create a 3rd unique community, but for over a week - I have not been able to create a new community. Is there a limit?

I click the “create community” button, and fill out everything and press “create” but nothing happens. It doesn’t say that I’ve been denied - it is like the button does not work. I can post and comment, but no longer create new communities.
