I'm currently growing a "mo" with some guys at work, and it hits me.
Huge, ridiculous moustaches for your character in the DDO store that only last for the month of Movember ... hmmm?
They could cost like a buck or less, and you could donate most (or all) of the proceeds to http://www.movember.com/ (check out the details).
Tax write-off, anyone?
Also, you'd have to talk to accounting about this, but you should be able to write off dev-hours for the moustaches.
Lets face it, DDO players are mostly male, and probably mostly hairy. Something like this would be alot of fun (imagine all the fem elves running around with Mario-esque handlebars). It could potentially make/save a lot of money for Turbine, increase image, advertise a bit to your most successful demographic, and help out some bro's in the process. Please think about it.
Just my 2cp, cheers.
