Roleplay groups?

Are there any active clans/groups which Roleplay in-game?

I'm aware that Warband MP isn't so RP friendly...I've seen that there is an RPmod in the works, so hopefully that matures (adds bigger player text/chat et cetera).

You'd possibly be interested in PRT.  A lot of their members roleplay, and IIRC they roleplay promotion ceremonies and the like in game.

(Just watch out - they're crazy. )

EDIT - Or these guys, but I can't say I've ever interacted with them.
