It seems that for the last few days commenting was not working on this site.
Umm....yeah.... I think that was my bad.
Over the last few months I have been tweaking the site in different ways, and apparently that caused the comments to not work right. (I wanted them to show at the end of the post, not a pop up) but when I discovered that even I couldn't post I figured that maybe others had had the same problem.
So if you wanted to post a comment and could not... it should work.
Or nobody cares.
