WPMU Dev Dashboard Plugin

Please help me figure this one out… CustomPress nags me to install the WPMU Dev Dashboard Plugin. I can’t seem to find a way to disable the nag.

When I install the Dashboard, you guys are flooding my site with WPMU fodder. Yes, it can be disabled, but it’s annoying.

The real problem is that I just discovered that I am limited to 20 sites to install the Dashboard even as an Elite member. So that means that after 20 sites, I can’t install the dashboard and I can’t disable the nag.

Help me understand that?? Thanks.
