I know Ive done this before but I can't seem to get it going just to add a couple links into the main menu to some misc pages.

I went to system admin>>blocks>>edit Mainmenu block>> but all it has is some html smarty tags and a view button.. no save button.

I tried to edit the template file itself but XOOPS just replaced it with the old one once I tried to change the permissions and upload.

Is there an easy way to edit this or maybe a module?

that's because you can't edit the default templates. You'll have to clone the default template set (via system admin -> templates) and edit the cloned main menu block template (first set it to be your active template set in the system admin -> preferences -> general settings page).
