Moving multiple posts from one category to another?

Hi –

I’m running WP 2.0.1. When I imported my 700+ posts from Blogger, they all got assigned to the “Uncategorized” category. Now I want to move large batches of posts into assigned categories. I’ve tried using the Batch Categories Plugin, but it doesn’t seem to work with WP 2.0.1. Is there another way to edit the categories for multiple posts, or am I going to have to move them ONE by ONE??

Thanks!
