Direct link in toolbar

Hello,

I am helping to oversee two separate, but similar blogs. I am trying to create a link in the toolbar across the top to the other blog, but the only way that I can add a link in that toolbar is to create a new page. But, if I make a page then I have to add text and such to it, which isn’t what I want, I just want a direct link to the other site. Right now I have a textbox set up with links in it on the right hand side of the main page so that I can have the links available, but that’s not ideal.

Theme is twentyten
url is powerofugly.com

Thanks!
