Question: Frontpage Displays

Hi everyone, I have a problem (not personal thankfully) and was hoping to get some help.

I have a MU site whose frontpage collects and displays the most popular posts in a manner very similar to

I wanted to change the default frontpage of the website to an “about us” page so that new arrivals can find out more about the site before entering.

So I made a new page and set it as the default webpage for the site (in the wordpress reading options)…Works fine the only problem is that I can’t figure out how to create a link off this new frontpage to the original frontpage that showed the collection of popular posts.

Can anyone help?
