I apologize for the site outage that occured the last couple of days.  I think it was caused when I was trying to test a site searching tool.  It involved registering DLLs and granting permissions, etc.  But somehwere along the way I broke the site.  And my attempts to fix it only made it worse.  After spending hours and hours trolling the Net via Google to try and fix it, I resorted to help from the source:  Microsoft.  It took a couple of hours, but we were able to track down the permissions that were incorrect.  So everything appears to be back online, but I think I will have to visit all the pages to be sure.
