Looks like you haven't been "welcomed" to Atheist Nexus yet, so allow me to do so. I'm just a regular but enthusiastic member, not an "official welcomer". Also welcome to the Welcome to Race, Ethnicity, and Culture group.
I see that you found the discussion groups. There are over 500, so there should be something for everyone. The search function helps. or just browsing through them. There is also the New Jersey Atheists group, if you are interested.
Anyway, once again welcome. Feel free to ask, if you have questions.
