Will there templates work flawlessly with Mambo 4.5.3?
And the second question is, in most of the templates here, the Main Menu shows up in 2 spots. On the side as usual and under the banner. How can I remove the main menu from under the banner?
1) Yes the templates should work fine with Mambo 4.5.3
2) Most templates use a custom menu solution as the default joomla/mambo menu systems are a bit lacking. to turn off the default one, just unpublish the mainmenu module in the "Site Module Manager"
