Nag Messages on Dashboard for new Sites

Hi all,

I'm using Pro-sites and having great fun configuring it and going through the forum topics (haha!). My question is general though, not specifically related to Pro-sites.

When a user creates a new blog, the first thing he sees is various nag messages from plugins that I've enabled by default. Is there any way to prevent these messages showing? Don't want to alarm users, would rather have a "Getting Started" widget in the dashboard which contains all the things they need to configure.

Here's a screenshot with all the messages I'm hoping to hide when they first log in:

Any ideas much appreciated!
Thanks,
Dee
