Since i start

Hi,

Since i start to use the fantastic WPMU i cant find the editor. I try to find the answer in the support pages but cant find any answer who solve my problem.

Before i had the editor in the normal place in the admin in "appearance" ---> editor.

But now is editor gone. Can you help me? I have a christmas-ad which i use to change in the editor and its little bit urgent to change this christmas banner.

I dont know if the editor dissapear after i install WPMU or if it is the last update of Wordpress who take away/move the editor?

Thank you!
