Hi there,
I wouldn't call this unique per se, but I bet there are enough interested people out there that would really like this hack.
The following is a link to an open source WYSIWYG editor that works on IE 5.5+. There is a demo page to test out, etc. here:

It seems pretty easy to add into vb... perhaps with a way to detect IE 5.5+? I'll have to test it in netscape and see if it works at all. At the least it would make for a great usercp option.
