All sites have a main menu with the links to the most visited
pages or important system areas. This block will appear as first
one in the left of your site. You can't delete the Main Block and
you just have one block.
This block is usefull to link to the different sections, like a
Web Links, FAQ page, Virtual Store, Top10, Special Sections,
Users Account Page, Topics, Statistics, etc. You can use HTML
code but not PHP code inside the Admin Block.
