Re: Integrating CKEditor 3.2 in TikiWiki 4.x
The latest version - Tiki 5 - has CKEditor added (FCKEditor, upgraded to 2.6.6, is still there), and is planned to be released in April. You can get a snapshot of the release now for testing but keep in mind it's still in development (http://dev.tikiwiki.org/Daily+Build). I'm not sure how to switch from the old editor to the new one; I don't see an admin interface for this. But using the new release should get you part of the way there, anyway.
