Sending user information from a CD

Hi everybody,

I created months ago an interactive CD using Flash. Now the client wants me to add a new feature to the CD, to get the user contact information, that they will have to type in before their first use of the CD.

My questions are two:
How can I send information from a Flash application in a CD?
How can I make it so this dialog box doesn’t appear every time the user uses the CD?

Could anyone please let me know if there are any tutorials, or give me some advice on how to do this?

Thank you very much for your help.
