I am playing around with YUI RTE and its looking good
I am currently Rebuilding my CMS and my needs for an editor are simple as the people using it wont have any html knowledge ,
So its basic text editing and an easy to use image uploader .
so far the one that best meets my needs is the spaw editor I just find it too difficult to implement.
TinyMCE like Fck has too many bells and whistles for my clients.
