role play?

[Joann]

//i'm not sure if this should exactly belong here, but considering the role play section is for role playing. . . this seemed like the best place (:

Yes, I've role played before. Not the best, but not the worst.
But. . . i've noticed that around here, you guys who role play seem to not only control yourself ((or your character)), but as well, other people/characters.
I've learned to role play in such a manner of which you create one ((or more)) character/s to use during the role play, and interact among the other character/s. Only controling the character/s you create/use/own. Whereas here, it seems that you ((we, us, whomever xP)) freely control whomever's character.

I don't exactly get it.
It's not how I learned, and it's a tad confusing. I'm just unsure on what to do, really XD
