First of all, let me say this: donating is (of course) not required. I started working on the program back around 6/15/2005, and it's taken me since then to get the project to the point it's currently at. I've put more time and effort into it than I even want to begin to consider; if you like the program and you think it's worth a few bucks to help out the broke full-time student who's writing it, consider a little "hey, thanks for making my life easier," donation. $20, $10, $5 -- whatever you're in a position to spare and feel is appropriate; regardless of amounts, the kind gesture itself is always appreciated.
