[wp-hackers] updating plugin admin menus on the fly

[Jennifer Hodgdon]

add_action( 'admin_menu' ) or remove_action( 'admin_menu') has to run 
before the admin menu is displayed on the screen for it to have any 
effect. So you probably need to do your POST variable processing 
pretty early during WordPress startup for it to work as desired.

Hope that helps / makes sense,
     Jennifer
