Since this has to be moderated before it shows up, I thought I better let you know that there is a problem in the Chat About It! subforum.  Apparently all threads except for the pinned thread about C# DNN got shoved into a thread about Cryptographic Exception.  To see the rest of the subforum you have to click on the summary info for the CE thread.  If you click on the CE thread itsefl this generates an exception.

I'm pretty sure I'm the inadvertant culprit -- it happened when I was attempting to add a post to the thread.

Somebody needs to fix it somehow.

FYI, Mike... you're not the culprit.  This bug has to do with trying to display the "Last Post By" field in the thread view.  If the userid value is invalid (a user unregistered), it causes this formatting problem.  Most folks wont see this bug, we get it occasionally becasue of our volume.
