There is an LS called Roleplay Lovers. It only has/had a handful of people I think. I ran into these players when I saw two of their members walking and chatting in say, through Uldah. I think I threw a snowball at one of them and ended up RP'ing for a bit. Anywho, I'm not sure how active they are or if they still play but you could try hitting someone up from that LS.
