People have posted about this before, but I agree. Of course, sometimes you don't want persistent expressions... And sometimes you just want to change the "default" one from /straightface. Because seriously... It looks like I'm always glaring at people.

But a system similar to the /emote motion, we could have /emote default, or /emote persist (or /emote stay if you want a less typo-able term)... That would be awesome. Just only allowed for facial expressions, and not on things like /laugh or /psych or /happy, because that could get annoying really fast :p
