Thanks so much EVERYBODY for helping with this, I'm pretty sure that I
have it fixed! (fingers xed) and again I sincerely apologize if any of
your were hit with spam from my server. As it turns out I'm fairly
certain that it was not IC at all, but a PHP contact form! (I will no
longer host postnuke sites, only IC or static html!)
Anyway, I think it is in line that I submit to a jury of my peers (IC
List -- even though I am only a glorified newbe) as to what my sentence
should be for being a bad host! Community service? Adopt a website? Free
hosting for some time to a non-profit? I await your verdict... :)
Thanks ICDevGroup and List Users!
