Ive' got one of my alts acting as mule/auctioner for my toons, and for a group of friends. What I'm looking for is an addon that will help me keep track of who sends what in the mail, without a bunch of typing involved. I've been approaching it from the standpoint of a trade or mail addon that would automatically check incoming mail, and note the sender, the item(s), and the number of each item items, but if someone has a solution that I'm not considering, please speak up!
Alternatively, if someone would like to try their hand at creating such an addon, I have a good set of feature requests.
