I rarely visit the forums here though I've been a member for a while so I hope this topic is ok.
I've created a website using Google services to host a PC Game DRM Database. There is a submission form so that anyone can add an entry, and there are several hundred games already included.
This isn't for any sort of profit. I made it because I was looking for a database like this and no one else had anything like it. I'm sure a lot of my fellow pc gamers would be interested in it as well.
The website is at www.drmdatabase.net
