Many people that have a passion about a topic go search out forums on-line. For instance, I am a Mac user, and use the MacNN Forums quite often. Now there is a forum for atheists! Atheistnexus.org. If you are interested in networking, contributing to the free thinking community, then check it out!

The other day I posted a funny picture on the subject of wacky religious signs. I just found another one for you!
Have a good day!
