Remove WPMU DEV Dashboard Nag

Hey,

I'm a brand new member here and I purchased my membership mainly to utilize the training videos plugin on sites to simplify training authors.

I only want to use the videos plugin on the first site I'm starting with. However when I install the plugin, it puts a nag up at the top of the admin area and I can't remove it. It says:

"Easily get updates, support, and one-click WPMU DEV plugin/theme installations right from in your dashboard - install the free WPMU DEV Dashboard plugin. (find out more)"

How can I remove this?
