So, join. You will meet more atheists in a week than you've met in your lifetime, especially if you live in the Bible Belt or other highly religious areas.
If you've already joined and you enjoy your time on the site, think about ways you can fundraise for the site. It isn't inexpensive to keep up a quickly growing social networking site and since we're using a service we could all afford to chip in a little either with our money or our time/service. Atheist Nexus is a valuable asset to the atheist community and one I hope to see grow so that others can find shelter in a world that is so often hostile to the unreligious.
I'll see you there, nancies.
