PAYCHECK... actually I just planned my paycheck. But I am donating some of my income to SourceOP this week (friday is payday) and it will depend on the following equation:

X-(Y+Z)=D

X is the size of the paycheck
Y is the price of my NintendoDS game adapter, and a memory device
Z is the price of THE ORANGE BOX
D is PROFIT
so:

(Size of paycheck)-[(price ofM3perfect)+(price of THE ORANGE BOX)]= Source OP's donation

My paychecks are usually around 170$... which leaves the team some good money...
