Thanks for your answer,
I thought about it but... IP address is not the best way to do it... Because
it changes.
I though using the date as a unique identifier... but what happens if two
persons subscribe in the same second.
The only way I can see is something like creating an MD5 from the users id
and then decoding it....
Ofcourse there is no way to decode an MD5... so that's my Question :-)
Cheers
