I'm trying to create a simple module that will ask all visitors to verify that they are over 21 before entering the website. Legally, my client is required to check that all visitors are over 21 and if they try to access the site by bypassing the  age verification page they will not be able to do so.

In order to do this, I have them fill a form where they enter there date of birth, check against today's date and make sure it's 21 or over. Once the user is verified I automatically log them in under one user account that I have set up. This account has permission to see all the pages while the anonymous account (unauthenticated account) has permissions to see only the age verification page.

Is this the right way to go about making an age verification page ? My biggest concern is if it's possible to have possibly hundreds of users log into the site under this one user account ? Or are there limitations as to how many can log in under one account ?

 

I would make a skinobject that checks if a age variable is set in the session. If not the skinobject would redirect the page to the verification page.
There is no need to involve the membership system if your users don't have to register in the first place.


Regarding what djbaldwin said about stubborn children. If you live in the USA you could get into trouble for not preventing access hard enough. you would need to verify age with a visa card. (just google on "age verification" and "mySpace" for more info)

I live in europe. I just state on the firstpage that this site is only for adults over 18 and that this site is not suitable for residents of the USA, wich covers my legal responsibility. I can just put an *enter here* link there, no need to verify anything
