I want to send a user a customized permalink to take him to a form.   When he click on the link, I want to pass his username or ID to the form so that the Form can show only information relevant to him.

For example, when a call desk captures a new "fault" based on a telephone call received from a client, I want to send an email to the client with a permalink that includes his TicketNumber.   If the client clicks on the link, he will be able to seen progress on that specific fault and he would not be able to view other tickets.

I this is possible and that someone can point me in the right direction.

Thanks in advance
