Hello
We're looking for ways to support simple HTML editing online too. You can use IFRAME tags in IE5, and make them editable - at which point they start to look like HTML editors - but they don't work in IE5 on a Mac. We found a page where the author said Mac users were "@!#$ out of luck".
So we're looking for maybe a Java applet that might do similar things... but haven't found anything yet. Just bold, itallic formatting and the ability to do H tags would be great. I'll post again if we find anything - have you had any luck yet?
