WotC sends Cease and Desist letter to website
Now it will be interesting to see if they come after the clones. The clones are definitely more direct competition than a site that indexed most of the 3e materials. If they do, I expect most clones to disappear. Even if the publishers are ok via the OGL, Hasbro has very expensive lawyers that can ruin their day. Who is willing to hire a lawyer to prove that he has the right to publish OSRIC, S&W, or LL?
In addition, WotC has started removing all their "classic" material from their website (3e and before). I recommend grabbing what you can if you want it.
