WordPress MU

I found an identical topic as below:

http://mu.wordpress.org/forums/topic.php?id=811&replies=17#post-4345

The problem is that I couldn't find wpmu-functions.php in my file directory.

I'm using wordpress 2.2.1. Has anyone encountered the same problem?

If you're using wordpress, you need to be over at http://wordpress.org These forums are for WordPress Multiuser, a different software.

We really need to beg Donncha to put "WordPress MULTI USER" in big red letters at the top of the box to start a new topic.

There's too many WP users somehow ending up over here, which in turn gets them into things they don't have.
