I just got Tiny MCE updated on MuchTall and I just thought I'd pass the update instructions on
1) Download and unpack Tiny MCE from http://tinymce.moxiecode.com/download.php
2) Move the folder /includes/tiny_mce to /includes/tiny_mce.orig
3) Copy the new tinymce/jscripts/tiny_mce folder to /includes/tiny_mce
6) Open your PHPNuke editor page
That's it! Now you have a rich text editor with advanced editing features right within PHPNuke!
