FreeThoughtPedia

FreeThoughtPedia.com is an atheist wiki designed to provide apologetic arguments for atheists.

As quoted from the about page:
 * What is FreeThoughtPedia?

FreeThoughtPedia is a central repository of philosophical, scientific, scriptural, and historical arguments and commentary on the Freethought movement. Our goal is to provide a resource for those who choose to attribute greater significance to what's rational and logical, as opposed to irrational, superstitious, mythological and unproven. While the critical thinking / freethought movement is not limited to any particular field of interest, industry, sector of society or belief system, the initial web site is focusing quite a bit on organized religion. However you will find numerous additional resources covering all aspects of skepticism towards the irrational and superstitious, from UFOs to Bigfoot to Political & Social Propaganda.

Unlike its Creationist and theistic counterparts, the wiki is inactive, with only a few occasional editors.
