Hi,

Answering my question, I wrote the cooke converter code attached.

I am using cookies because is that we have a web based bullitin board here,
behind the firewall, that uses a cookie for authentication, nothing
secret, just to ensure posts have their owners names attached so
I feel cookies are an apropriate level of security - no matter
wat you all say :-)

-Steve
