I noticed that as well, although I thought it was something I had done wrong, so I corrected it. I still have a problem with the AIM field though...
I get the following URL (404) when clicking on the AIM logo by someone's post...
aim:goim?screenname=whoever&message=Hi.+Are+you+there?
Is this because I don't have AIM installed... Because I would think there would at least be a default page for those who don't if this is the case.
