Hey everyone
I know most of the forums you just pointed out. I really like the how-I-learn-any-language Forum and Unilang and Omniglot are awesome too. The WordReference forum is a quality place as well and “traffic wise” it is just an incredible place with millions of posts!
At this point I would like to mention my own language learning forum, which is http://www.linguaholic.com.
We have a General Language Learning section as well as sub forums for many different languages. You might want to have a look! I will make sure to try out the language forums you mentioned that I did not yet come across!
