Seperated blog content

Hi all,

you can see my (starting) site at: http://blogmd.netai.net

I uploaded a screenshot that I edited with MS paint to show you what I would like to accomplish/ The screen is at: http://users.pandora.be/dollaarke/screenshot.bmp

The question:

(In blue): I’m going on a journey for a few months. I would like to have a Traveeling-blog next to my regular Blog. The Idea is that there is a link at my right navigation bar. Even the category “Travelling blog” should be available. How can I create posts and link them to the page “Travelling” with wordpress automatically giving me the option to point it to a category, adjusting my archive BUT NOT automatically adding it to my recent posts???

It has been quit a challenge for me and I don’t seem to get it the way I want? I was hoping you guys could provide me with the right plugins or other methods to do so…

Tnx in advance

P.S. If you have any suggestions on how to start… plz do tell!
