admin notice

I'm a bit irritated that when I pay for plugins I still have to deal with advertisement being pushed down my throat.

I am referring to the constant red admin notice to install the WPMUDEV installer plugin.

I have gone through all the plugins to remove this irritating red bar but there is still something hiding in PRO SITES.

Can you please point me to the file / line number where I can remove the admin notices/wpmudev advertisement !

(And PLEASE stop pushing this so hard, A one time notice on activation of a plugin is acceptable, but the current forceful notification is just not good programming practice )
