What would you say are the most active/popular rp's in the glee world?
Hmm, i can't put up most active because i'd have to be an actual member, but i'll sugest some that are popular in the roleplay world. Some are based on confessions we've got over the last year on Glee RP Confessions. I would suggest my own, but don't want to self promote, if you do want to see mine, see staff page there.
Talking Gleeks - One of the very FIRST ask roleplays (make sure they are the original Talking Gleeks and not a copy)
Breakout Gleeks - Their original Kurt inspired me to roleplay. Even though not in roleplay anymore, they still continue 1x1 with the original Blaine.
We Keep Marching On - I was a member here for a short time, but it has been going on for a while and is really good.
Ok those are all i'm going to name because i don't want to self promote EVERY single one i think has been going for a while etc. Also can't remember them all.
