I actually started a Skype Group for Korean learners about half a year ago. We have beginners, intermediate learners, and a few natives. Sometimes we do challenges (a.k.a "homework") together but usually, we just chat and ask each other questions here and then. If anyone wants to join, just let me know. Quite a few of the members watch dramas, too, actually. ;)
Apart from that, I'll definitely participate in a Korean-only thread here in the forums! Sounds like good practice.
