When I look for instructions to upfgrade in the README file, I am sent here:
http://codex.wordpress.org/Upgrading_WPMU
Which tells me that instructions are needed:
It does point me to two URLs:
1. http://mu.wordpress.org/forums/topic.php?id=8885
2. http://ocaoimh.ie/2008/07/09/wordpress-mu-26-beta-1/
None of which give me any instructions.
Is there any advice out there?
