So, I've seen a small handful of unique race/class/alignment combinations in the past 1-2 years...

I don't remember specifics, but I think I remember reading something about those characters having roles that were pre-approved and/or pre-screened in some way.

Or were they all pre-written by Imms for a specific quest purpose?

Not to be too full of myself, but I've had my fair share of role contest wins and unique empowerees....

If I were to come up with what b I think is a great role for a non-standard race/class (with probably built in cons)....is there now a chance of getting a chance at giving that char a try? If so, how do I go about that....email all the imms? Just the Imps? Pick an immortal and start by just going to them?

she's pretty receptive of good roles and will run it up the flag pole. they'll turn some down (such as neutral shaman). just depends what you're asking for
