Here’s some good links for all you fellow mythology freaks, in case you weren’t already aware of them.

Of course wikipedia has tons of info, here’s a List of Mythologies to start off: http://en.wikipedia.org/wiki/List_of_mythologies
And at the bottom there’s links to other mythology related lists (creatures, deities, objects, etc)

Along the same lines there is: http://www.pantheon.org/ which is another encyclopedia of mythology, very extensive.

http://www.loggia.com/myth/myth.html – has a decent forum to chat on (as well as basic info on Greek, Roman and Celtic mythology)

Another forum: http://www.mythforum.net/

In my opinion, the best Greek Mythology sources are:
http://www.theoi.com/
http://messagenet.com/myths/
