This probably is not the best way to go about getting people to join your roleplays. People naturally avoid anyone that seems like they are going to be a sulky whiny butt. .__.
You need to put yourself out there, advertise, and be proactive to CONTACT OTHERS! Lots of people are very shy!
And RESPOND TO OTHER PEOPLE'S REQUESTS TOO! Either through replies on their threads, or sending them invitations on their profiles or in Conversations. Waiting around for people to notice you just isn't enough sometimes. You gotta be proactive!
