Reported on the tiki dev site todo list. Here it is again. Was using 1.9.1
and noted some was able to by pass the validation process in the
directory feature. Upgraded to 1.9.4 and they are still able to bypass the
vailidation. Here is the very long text that they are putting into the site
description and which I suspect is causing some kind of buffer over run.
I have the text that may be causing the problem.
