I don't know why but on some peoples name if you click on it you there is an option to pm them. On other peoples there isn't. It was driving me crazy because the person I wanted to pm didn't have that option. So I found that if you click on the "my rollitup" option near the top of the screen there is an option to send a private message. You have to know the name of who you want to send it to though. It actually gives you all the names it can be as you go along. It took me like 2 days to figure it out and countless hours. Good luck. If you can't find it let me know and I'll try to be more specific. Good luck.
