If you are using my PHP CMS Text code, and would like a WYSIWYG editor, then this might help.
Beware, this script is far from being finished. Quite a few features still need to be implemented (e.g. tables), and I hate to think what IE will do with it.
If you think this script might be useful, you can download a copy of the source code.
To use it, just include this file, and add the "jsBbTagWysiwyg" class to the textarea. You might also need a few functions from my main JavaScript file.
Thank you for looking at this code, any feedback would be greatly appreciated. If you would like to use this code, please read the licence it is released under.
