Hi Johan, over the last five years, I developed an WYSIWYG editor based on TinyMCE which is part of BlueSpice [1]. You can try it in our demo [2] (User: Testuser, Pass: hallowelt). I’d say it’s pretty stable, we have a base of several thousand users in enterprise contexts. BlueSpice including the editor is GPLed and you’ll find a download link here: [3]. Maybe this one could be a basis for your instance? If you find something that needs to be improved, me and my team will be ready to do so in a short time frame. In any case, I’d be curious about what you think of BlueSpice J and the editor. Best, Markus [1] http://www.mediawiki.org/wiki/Extension:BlueSpice [2] http://demo.blue-spice.org/index.php/Hauptseite [3] http://www.blue-spice.org/
