Top menu position

hi is there any way to change the menu on the template and replace it with another module?Have tried to but the module position is nowhere to be found.How can i do this?

Hi,
if you talk about main menu, under logo , which you called top menu - to change it -- you have o customize php code of template.
If you don't feel comfortably with such a changes you can hire somebody, who will hep you. (use PM if you want to choose me)
In general you have to remove our menu code and insert there a new module position, and publish new menu module.
