Think about how many DVDs you've gotten from myspleen.com, then think about how much you would have had to pay for them through other sources (if you could even find them anywhere else).
I think that donating $10 through PayPal is a very small price to pay to help keep myspleen.com online.
Go ahead, help out gang. Do your part and keep MySpleen! and all of the great torrents there alive.
