WordPress 3.0 / MU issues Need Help

Hey Guys,

I’m currently having trouble with my A2SM.com blog. 4 main problems:

1) When I login to the site not as the main administrator I am unable to embed youtube videos and such. This is a big problem because I need to be able to let other people who write for us do this as well. I currently have the Unfiltered MU plugin running to allow embedding of video. But it doesn’t seem to be allowing anyone other than the main Admin to embed any video and even make changes after the fact.

2) I’m currently running the multi-user version of 3.0. I’m also have a problem with updating existing posts. Right now if a non-admin writes a post it won’t update in subsequent revisions. I don’t know what the hell’s the bloody problem. Ideas folks?

3) The Google XML sitemap plugin currently doesn’t work with the MU version of 3.0. Does anyone know of a way to make it work or know of another plugin that will work with it?

4) At the top of the blog I get this warning: The wp-content/blogs.php file is deprecated. Please remove it and update your server rewrite rules to use wp-includes/ms-files.php instead. How do I do this.

Sorry for the long post but I figured I’d get them all in one thread.
