vbulletin, proof of purchase certificate.
 

wouldnt this be a good idea??

get a certificate of purchase with expiry dates etc..

and perhaps invoices of charges etc..

just so the customer has some sort of peace of mind he owns a license etc..

No. It would cost money to add a physical aspect to a virtual product.

Isn't the email you get with your customer # and password proof of purchase?

Pretty sure he means something physical. I do think a trophy would be nice :D

filburt, you'd probably just keep the trophy 13 and 1/2 hours past you expiration date, anyway. :p

It would take too much time, money, and effort to do that - Jelsoft have hundreds if not thousands of clients - imagine the printing costs.

piffy, just email them a picture and let them print it out :D

But what's the point of the certificate??? Especially if you print it out yourself - you might as well make your own.

It is not needed to check for piracy. There are electronic ways to do it.

what if people loose there email etc...?!

Then they can retrieve their customer number/password instantly.
