I know flash can’t do it directly, anyone have a good way to do this?

I created a flash projector that autoruns on a cd, there’s a signup form on the disc. When the user signs up, the info is sent and stored in a database… Now, how can I prevent (as best I can) the user from coming back and signing up again? If I could write to a file, or to the registry, I could at least stop them from signing up twice on the same computer. Any ideas??

Thanks in advance.

you can also use Flash’s [Shared Object](http://www.macromedia.com/support/flash/ts/documents/local_so.htm) which is like a Flash cookie.
