With the Queen of Hearts there really isn't any specific volunteering per se. She yells at her Mirrors to get a job done, and expect them to do it, independently, without taking up any of her valuable time to bother her with specifics.

IC she did mention that she expects some of her Mirrors to "make certain that the misplaced Reals do not make nuisances of themselves", so presumably that would sound like as good a reason as any to go for it.

OOC all I can say is absolutely yes, go for it! Have fun, knock yourself out. Make a log for it or try catching people in their posts, plot in advance or see what comes up, whatever strikes your fancy.
