Online Language Learning Communities

Community
I’ve decided I’m going to try out the free features of the online language learning communities, and report back with my findings (as well as prices for the pay features). But the first challenge is just finding all of the language communities. These are the ones that I plan on reviewing. Can anyone add others to the list? I know I must be missing some!
