[Mediawiki-l] WYSIWYG Editor Question

[Rowe, Dolores A]

The WYSIWYG editor (Mafs) at this url
http://www.mediawiki.org/wiki/Extension:FCKeditor_%28by_Mafs%29 contains
the following warning:  "It may lead to security and technical problems
as well as data corruption."

Is there anyone out there that can give me examples of specific problems
the editor may cause ?
Or what can happen with it to cause data corruption ?

I have some users that really want to implement it, but the warning
worries me, so I am looking for
justification for the warning.

Thx for any info,
Lori
