www.openrpg.com: Free software for the excellent OpenRPG modus of online gaming.  Check their site out and, if you're feeling as generous as they are, donate a few coppers to their cause.  I say "as generous as they are" because OpenRPG is free software, and the folks that make it could probably put their genius to work doing other, more profitable things rather than continuously better an already great online gaming modus for we nerds of the world.

www.geocities.com/adndlegends/:   Player/DM antics, weird and silly things that happen in campaigns, stories, favorite characters, you name it.   Contribute your own fables, foibles, humorous stories, favorite characters or any kind of funny/amusing or just plain interesting game-related blurble.  Contributions of money are also welcome, so I'm told.

There are a lot of useful AD&D 2nd edition materials on this site. Most all of it, however, won't be of any use in my own campaigns.   Never-the-less, if you're looking for a good site with downloadable netbooks, character sheets and other nice things to have, check it out, and be sure to drop the owner of the site a line to thank him/her for having such a useful site.

http://www.opengamingfoundation.org/srd.html -  This site has a lot of excellent 3rd edition info.  The layout isn't at all impressive, but the information is solid and abundant.
