how to delete a message that ended up on the web (by way of Histonet)

I was looking through some web sites on the web and located a message that
I posted on the histonet last year (March 2002).  We were looking for a
Mohs tech at that time.  Now this message is out on the web with my name
attached saying that we are currently looking for a tech, which is no
longer true.   I had no idea that this message could have ended up there. 
How can I go about having this information removed?  Any information would
be greatly appreciated.
