Hi Deirdre, welcome to Atheist Nexus. It has been a long time since we had a Deirdre on this site and I am getting used to the fingering of the letters of your name again. This is a lively group with many discussions taking place. I started by going to "Groups" above and found topics that appealed to me. he Forums, Blogs, Photos, and Videos have other ways of getting acquainted.
A very good Group to start with is "Hanging With Friends". Look along the right-hand side of this page and you will see the Comments and Discussions taking place today. I hope you enjoy your time here. I look forward to getting acquainted with you.
