Alexiel is right. It can't be done.

But I have a suggestion. You can create 2 blogs. Say, the 1st one is joeydc.blogspot.com and the 2nd one is joeydc1.blogspot.com

Blog 1 will only have a main home page which you can design to act like a front page with no blog posts. But you would have to switch from using blogger templates to full html and do some text/script writing yourself.

Then all URLs in Blog 1 are actually directed to Blog 2. And the surfing around will continue in Blog 2. You can group posts into categories, eg. news, travel, food. And then note down the URLs in Blog 2 to those categories. And then place these "category URLs" in Blog 1. When a user click on "News" in Blog 1, he will be directed to all the posts under "News" in Blog 2. No one will ever notice the difference as long as the flow of pages is within the same browser window.

If Blog 1 is your "home page", you will need to write a URL link in Blog 2 that says "HOME", which links back to Blog 1.

Hope that's not confusing.
