On the off chance that anybody noticed it, sorry for the interruption over the weekend where it was impossible to log into the website.  The newest version of DotNetNuke was released on Christmas Eve and I tried to run the upgrade, but while it appeared to go properly I quickly discovered that the login and register pages effectively disappeared.  Earlier today I restored the site back to where it was before the upgrade, and I am working in the DNN forums now to find a resolution.  Sorry if you wanted to post something and were unable to, but everything should be fine now.
