New Admin tab
I would like to make a new admin tab, similar to the "help" tab. Basically duplicate it, and repopulate it with my own content.
I would like to educate my clients on the full range of other services I can offer them, and include direct contact information for any support issues they may run into. A new tab would be perfect for this, where it contains my custom content. This content would be static, with some images, etc. Nothing fancy.
How can I pull this off without destroying anything else in the admin section?
