Just a quick note that JCE 1.5 for Joomla! 1.5 is currently in development and will be released soon, although an exact release date is not available at this time, expect somthing in the region of 1 to 2 weeks from now. It will initially be released as a beta.
This is a complete rewrite of the JCE Admin Component and Editor Mambot, designed around Joomla! 1.5's new MVC API. It is being designed to work better and faster than previous releases and will include the new TinyMCE 3 wysiwyg editor
Although not all plugins will be available on release, all currently available plugins will be redeveloped for JCE 1.5 where neccessary and a few extras will also make it into the list, one new one for members, and one new one for everyone.
It will be worth the wait.
Thank you for your patience.
Please note that the current version of JCE is not compatible with Joomla! 1.5
