WordPress MU

is it possible to change the URL for admin blog posts so indtead of mysite.com/blog/2008/01/13/hello-world/ it would be mysite.com/<something else here>/2008/01/13/hello-world/

I'm looking for something similar - although I want permalinks to be automatically activated for all blogs...

Permalinks are activated as pretty for each blog. Do you mean you want to change them from /year/month/day/title/ ?

In the database table wp_1_terms, change the slug from "blog" to what you want.

That will only work on subdomain installs by the way. subdirectory installs have no such flexibility and you would need to modify core files to do it, for example wp-admin/options-permalink.php has it hardcoded.
