Hey, I don't mind offering to send thank-you postcards for donors- I've got lots of spare stock that I don't mind using for this purpose.

Also, know a programmer who sorta owes me cause I do art for his things (for free). Maybe I can ask him if he can code a plugin or something for the post format. I know Proboards has something like it, so I imagine something could be scraped together for vBulletin. I'll ask if you want me to- no promises though. xD
