Menu labels can be changed via the menu_label Array in the actionscript in Frame 1, labeled "buttons".

From the code:

var menu_label:Array = new Array("Homepage", "Products", "Services", "Awards", "Company", "Contact", "Templates|http://www.flashmo.com/page/1");

Syntax for labels: "Page Name|URL"

For contact setup, edit the "send_email.php", it is nicely documented so it should be easy to edit.

For the music, it is commented out at the bottom of actionscript in Frame 1.

Edit this code:

var bg_music:Sound = new flashmo_music();

Change "bg_music" to the linkage ID of your music in the Library.
