Well, only FORUM roleplaying I can call as "roleplay" that I had in my life was when in different forum, in Off Topic thread, with some random post, I accidentally started grand event, when many people pretended to be possessed by evil spirits, and so, "roleplay event" started and lasted for a pretty long time for dozens pages. XD
Here, I signed for Roleplay in style of original Movie, but still didn't make a single post. :O
In real life, I didn't take part in some roleplay events. Not counting childhood plays when I was at kindergarten, of course.
