In order to fix a login problem that some people usingInternet Explorer were having, the login page and underlying process is being changed. The only change that you should see is a slightly different login selection page. You will login the same way you have in the past.
The change will take place at 7:00 am on Sunday, October 7, 2012.
Here is a screen shot of the new login selection page. You can see that it is almost identical to the current page.
