Did you have a look in Bulld --> User Interfaces - Style Editor on the Login Page
you can change the logo, message and title there.
On the other tabs you can set what else you see.
hope this helps
Hey NSWOSR, we tweaked that title a few weeks ago but it doesn't seem to have any impact on the actual site title (the wording that appears on the tab in the browser). That field seems to control a text field that displays in the middle of the login page.
Thanks Terry - that did the trick!!!
