Click the "Help" button - next to "View New Content".
Scroll down about half way to "My Assistant" and click.

It says:

The 'My Assistant' feature can be accessed by clicking the link of the same name in the board header. This tool provides quick links to many important areas on the board, as well as quick access to common features.

My Assistant has four seperate feature tabs:

Information - this tabs offers links to the overall and daily Top Ten posters, as well as your last ten posts on the board. You can also click to view the Moderation Team.

New Posts - etc, etc.

There is no "link of the same name in the board header".

(Plus they can't spell 'separate' )

Thanks to SeaVisionBurma for where to find some of the links:

- they're on the main Forum page!

So maybe just the "Help" text needs to be updated.
