In a recent discussion with a freshly converted atheist, I was providing some information to assist in understanding apologetic arguments and such. A nonprofit group that I love here in Texas is the Atheist Community of Austin. They host a public broadcast show, pod casts, and web casts. They have great information and the programs are usually very informative and very entertaining.
If I may suggest...
Or one of my favorite counter apologist sites (run by the ACA)
Just sharing information... I don't work for them or an ad agency or anything like that! ;-) I just find them to be very structured in how they present the information.
