Other possibilities, like renaming stuff...

Hi all, few quick questions, Is it possible to rename some of the menu options, and add more and have them set up like separate blogs. For example to remove goodiepool, change name of imagepool to like pictures, and add more different menu options, like a, b, c, d which all lead to their own blog like page, and not having anything posted to the homepage but keeping it as is with only minor changes every now and then. Thanks all in advance. Jak.
