So as a new user, I didn't see a search function, so I hope this wasn't suggested already, but upon signing up, I assumes incorrectly that I had to join the clans I was interested in.

It was painful to leave the ones I don't care for after the fact, and I think it would be much more friendly to be users to have an opt in by default option, with a join all button at the top of the list.

I hope this suggestion helps! The app in general is very nice as a reddit alternative, and I hope it can gain more support.
