WordPress MU

Well after a series of Hurdles Im now at the stage where I can start people creating NEW Blogs But... the password generated for the new Blog does not work!
I reset the password the new one gets mailed
I use that and still no luck whats the fix

I really don't want to delve into the data base every time some one sets up a new blog this cant be a new issue

I can only find reference to admin log in problems But i do not have that problem

It all works well Well almost I do have a theme issue but will address that later

Fixed this problem onto the next this is a painfull learning curve Make sure you add aa comment where the new bloggers fill in there User Name lower case only this was not easy to find but there is a whole thread on it
