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

[Robert R. Marsh, SJ]

Callum and Jennifer,

I got it to work by hooking into the 'init' action. It took a little playing
around with action priorities too. Until I boosted the priority I could
remove the extra menu but not add it. Anyway it's working now.

Thanks, 
Rob
