...adding extra menu items to the template is not recommended unless you really know how the entire site is scripted and what changes have to be implemented - it takes a professional designer about 100 hours to put one together - so this would be a huge job - from the help files...

Adding/deleting Menu items/titles/sections
Unfortunately although you can expand the number of pages in each of the menu items, it is very difficult to add or remove main menu items. Also, though some Site templates would look ok, others will look off balance, so it is probably best to leave all the items and put a 'Coming Soon' or 'Under Construction' message in sections for which you have no content at this stage.
