Page & the external Links

Hey dudes,

i got a question. First of all i got to thank wordpress for that awesome product.

So now my question. I use a real cute design design which presents me my created Pages on the right menu bar AND automaticly shows up that pages on the top of the page in a horizontal order.

In that case that I am serving more than one Site (one is the Blog and one is my Gallery-Site with another domain) I need to set up a direct Link to the Gallery-Site.

At that moment i have published a Site which contents a Link to the Gallerys. But thats not that fine solution it should be.

How am i able to set up a direct link to another Website that will be displayed as a part of the pages listing?

THX for your help …
