Yesterday I realized that I was having issues with anonymous users posting comments to my CS site. After going over the code a little bit, what I didn't realize is that the bug is a custom skin bug. (ie a skin that I wrote was missing one line containing a specific control.)
After a little searching I found someone with a similar problem, and Alex Lowe pointed them here: http://communityserver.org/forums/491886/ShowPost.aspx#491913
And it worked. Yay.
