[wp-hackers] WPMU Category Table

[Tim Schoffelman]

Quick question, and this may have been asked before, but is there a specific
reason why there's a shared wp_sitecategories table, instead of a table
broken out into wp_2_categories or something like that. The reason I ask is
that when trying to develop a theme and creating a category-[CATID].php
file, such as category-6.php and then implement that theme on a different
blog, the category ID changes. Now I know I can just rename the file, but
this issue spans into many different scenarios when creating a theme. Any
thoughts?
