There are literally too many to count. Some sites will focus on the 'mainstream' strange creatures like Bigfoot and UFO's and Nessie, and others will go as far into left field as you can imagine. You can look up sites about fairies, chupacabras, skyfish (those are cool), ghosts, wisps, possessions, you name it.
Wikipedia has some good stuff, but just type whatever creature you're looking for into a google search and you should find loads of information.

i just did a quick search on google for "mythical creatures forum" and found this site:
http://www.mythicalcreaturesguide.com/thread
don't know how good it is, you'll have to find that out for yourself. i'm a little skeptical of things like these.
if this site is not what you're looking for, try some other ones found by google.
good luck.
