Hi,
It's straightforward to do this for all modules:
1. login as an admin
2. Click on "Administration Menu"
3. Hover your mouse over the "System" icon and select "Modules" from the pop-up list
4. In the right-hand pane, edit the name under the module's icon to whatever you want it to be on your "Main Menu"
5. Click on the "Submit" button underneath the list of installed modules
