We have multiple CruiseControl (CCNET) instances running on our build boxes and we've been wondering how to differentiate which one is which so people can know at a glance which one they are pointing at.
This turns out to be relatively easy. In a typical CCNET installation, there's a \cruiseinstalldir\webdashboard\templates directory. Inside it you'll find a file called TopMenu.vm. Open the file up and after the last '#end' put some literal spaces in and type the title of your CCNET site with some plain html formatting to make it obvious (make the font bigger and bold, for example)
...save it and refresh your dashboard page.
