Greetings, Aparna! I notice you haven't been active at Atheist Nexus since Jan 2010. <sigh> Sometimes it can seem a bit fragmented, with different groups for every interest. Please consider a group for socializing, where we talk about whatever's on our minds, Hang With Friends. :D You might feel more at home.
See, originally, we tried having an omnipotent, omniscient uber-being whose job it was to inform every atheist that Atheist Nexus existed. We got halfway through building it when we realised, embarassingly, that such a creation would make the site obsolete, and we already had all the .css worked out.
