Free D&D

So I was looking for information about an old horror comic book when I stumbled across the Wikipedia page for Tomb of Horrors (link contains spoilers). Instead of containing information about a comic book, it was devoted to a Dungeons and Dragons adventure. Said adventure is apparently infamous the its sheer number of deadly traps and reputation as a player-killer. Despite its apparent lack of monsters, I thought that some readers might be interested to know that Wizards of the Coast has put up a version (revised for 3.5th Edition rules) as a free download.

After poking around Wikipedia some more, I managed to find two other monster-related free downloads: a never-published supplement for the horror-themed Ravenloft campaign setting and the monster-filled adventure, White Plume Mountain (also revised for 3.5th Edition rules). I should note that I personally haven't downloaded or opened any of these. As is the case with all links to downloadable content, open them at your own discretion.
