I want to contact another player named [APO]Master___Mind, but he is not online at the moment. So I left him a few Offline PM Messages. Will he get a Notification that I sent him Offline PMs the next time that he logs in? Or could he log in without realizing that I left him Offline PMs and never realize it, if he doesn't check his PM Inbox? For example I usually don't check mine.

Is there a way to contact him by email instead?
