You could do a full Pump Up the Volume style rant in your XP/Renown/Downtime thread, and put just one or two excerpts in the public renown thread.
You'd get to amuse the staff, at least? And yourself. I have a ton of fun writing my Downtime for my Hidden Flame character, because she sort of . . . she's not allowed to show the full force of her personality at game. Even a half-measure is getting her a visit to the Philodox Council. But I get to write it all out in her Downtimes, and that's very refreshing. Also fun writing stuff in Shulamith's character area, about all the things she can't or doesn't talk about publicly.
