Broadcast MU isn't working for me at all …

I have a simple question. I’m trying to get the Broadcast MU plugin working so I can post to multiple blogs at once. Not working. I see the list of b logs in the admin page sidebar. I click the blocks i want the post to be made on, but the posts never show up, not even as drafts.

I’m running a citizen journalism site, and I occasionally have posts that can run on more than one blog and I’d really like to NOT have to copy and paste them all.

Help!
