Welcome, Erica! Glad you could join us. :D Hopefully you'll like what you find here, and stick around after you finish your article. You could solicit interviews by posting on one of the forums, which is done on the main page.
After you've searched for topics of interest in "Groups" above and in the "Forums", don't forget to look at recent activity which hides along the right margin of the page all the way at the bottom.
On a personal note, I've developed an animated gif technique, sort of “pull quote marries slideshow”. Samples are scattered across various groups, but you can find them easily by going to my twitter account. Each tweet has a link (after the description and before the hashtags) to a visually rich example here at Atheist Nexus. If you like them, please follow me
Hi Erica Welcome to this world of rationality and peace, where pure common sense helped by science is all it needs to find the freethinking wisdom common to non-believers and critical thinkers like us-----and hopefully you. We invite you to join the busy group "ORIGINS: Universe, Astronomy, Life, Earth, Humans, Religion, Gods, Atheism, Evolution, Darwin..." with 730 discussion topics and 3700 members. http://www.atheistnexus.org/group/originsuniverselifehumankindanddarwin Terry
