Ya don't have to if you're morbidly against people IMing you.
But most of the ARic populous that rp here IM eachother to set up the different rp sessions. So if you want to rp or want to rp with someone specifically, IM's are far faster and more efficiant than PM's.
If you don't have aim, get it XD
All that saying, if you post a profile up in the rp's (any of them) make sure to put your aim name at the bottom of the profile so that people can contact you for RPage. Ya know?
