Offline: Face to face. I'm much better person face to face, than via phone, et cetera. I just often run out things to say on phone ( depends on the people though), but never run out of things when face to face. It's hard to explain.

Online: any way you can contact me is just fine. You are most likely to reach me via PM/email though, since I'm not on messengers every day, and when I am, I normally use it only 30minutes - 1 hour. Final Fantasy 11 on the other hand... Yes, you can contact me in FFXI easily, if on the same server.
