Thanks Rodney,
I looked at the modules you mentioned but it doesn't look like they have what I need. Also, I think I may have to clarify what I need:
For legal purposes, my client needs to verify that website visitors must be over 21 to enter the site. When the visitor first goes to the site they are asked to enter their birthday before they can navigate to the rest of the website. Otherwise, they will be presented with a message that warns them that they must be over 21 to enter.
The tricky thing is that my client does not want to ask every visitor to register for an account. Therefore, I can't see a way for me to set up my portal to authorize users, without asking them to register. This is important because if they try to bypass the Age verifcation page they can (i.e by entering a url like this www.website.com/section on their browser will bypass the default page which is the age verification page).
So my question is: is there a way to create a module (or purchase one) that will allow me to "authorize" all visitors who pass the age verification requirement without requiring them to set up an account. Perhaps, automatically log in the anonymous user as some "authorized" status so they they will be able to navigate throught the rest of the site, but at the same time not be able to do that without first requiring them to go to the age verification page. Is this even possible ?
I hope this clarifies my issue. Any help is greatly appreciate it.
