Some of these I'd call "barbarian sites" as they have other than game info, but anyways:
* http://www.marvunapp.com/Appendix/appconan.htm - Marvel Comics list of Conan characters
* http://www.barbariankeep.com/index.html - The Barbarian Keep (not really game site)
* http://www.conan.com/ - "official" Conan site
*Other game supplements
- Mongoose thread with links & notes in it.
& Red Tulwar
have neat sites where they lists adventures, they and others have outlined adventures as well. As I haven't seen posts from either in a long time, I don't know if they'd want their urls revealed, I better not link it here (but if you search this forum you'll find posts where they included their urls, FYI.
