Like I mentioned, we do use a journal server (similar to LJ) for the RP because you can get comments left on entries or scenes sent to your email and you can email directly from your email account. For fun we do use AIM and Chatzy and do group scenes, chat rooms, etc. Its seriously a lot of fun and the other RP'ers are super super active and have been role playing in the Glee verse for close to two years so you know you won't join and then have the game die out.
The roles we are looking for are: Santana, Puck, Tina, Mercedes(for an awesome bff line with Kurt & Rachel), Artie, Mike, Ryder, Kitty(possible line with Jake), Dani, Unique, Cooper, Joe, Sugar, Adam, Brody, Chandler, Warblers & more.
If you would like more info, the link to the community is here: http://slushees.insanejournal.com/. I can also answer any questions you have and will gladly walk you through the process of joining if you are interested.
I'll delete this too so it doesn't interfere with your muse post. If you have any questions though, hit me up here. Really hope you will consider joining. We would love to have you.
