This Forum is actually based off of an even bigger forum that is roaming around in the chatter box. AND that forum is actually based off of a website that utilizes postcards with anonymous secrets sent to the owner.
The website :
PostSecret

Refreshes with new postcards on every Sunday. (I'm a regular)
Postsecret also has forums much like my own guild but it requires a membership. Since you are already part of Gaia, I Present to You the Dirty Little Secrets Guild Forum. If you would like to read more "secrets" then click either the above or go to the larger forum in the chatter box:
