On the whole there can't be much that atheists have to discuss between themselves not covered by non-atheist specific sites. Hence, possibly, the posts about reopening the forum to the religious.
On this forum new topics on atheism itself are very rare - we just get the same set of repeated arguments on the Searching for God thread.
If there is no "god", does it matter at all? You can attempt to dissuade believers, but if faith is not based on reason, to what end?
