Through the end of the month, DriveThruRPG is offering an amazing deal. If you donate $5 or $10 to them, they will double your donation and give it to Doctors Without Borders. If you donate $20, it goes to DWB, but you also get almost $1,500 worth of PDF gaming product! There's a lot of good stuff in here, including the Serenity RPG and core system, the Spycraft first edition (of which I was a beta tester and mentioned in the credits), a treatise on how to game with children, just all sorts of wonderful stuff.
So many people wanted to donate product to this collection that finally DriveThru had to say 'no more' and cut them off. On top of that, they had to hire additional server capacity to handle the demand.
And you'll help Haiti: by the time you read this, they may have topped $150,000 for earthquake relief.
One FYI: don't expect an instant download: they'll send you a key in a day or two. I did my purchase about six hours ago or so and haven't received the download info yet.
