Ok.. You can do this:
1 - Rename admin.cgi to adminSomthing.cgi

if you want to use different template set then continue (else go to number 6):

3 - rename templates/admin directory to templates/adminNew
4 - Replace (using fileMan) all the contents in adminNew of admin.cgi with adminSomthing.cgi
5 - Go to Links.pm and change the template set in the "sub Admin..." procedure to read: templates/adminNew instead of templates/admin


6 - Replace template/admin inside adminSomthing.cgi with the new template path.

Now you can access your admin with this link:
http://www....../admin/adminSomthing.cgi
