APEX

I've been reading how great and expansive the security is within APEX.

This is great, but I can't seem to find an example showing how to allow a user to register for access.

Here's what I want to do:

1. User goes to URL
2. User does not have login and password
3. User clicks on register for account link
4. User enters basic information
5. Information is cross-referenced with a table in the database.
5a. If no match is found, the user is shown a message.
5b. If a match is found, a validation link is generated. This information is then e-mailed to the user.
6. When the user visits the validation link, the account is activated and they are e-mailed a system generated password.
7. Should the user NOT visit the link, say within 24 hours, the account is removed

Is this possible?

Thanks,
Chad

PS: I'm using APEX 3.0.
