Existing free users aren't registered

Hi all
On my site I have only free level #0 users at the moment but will have paid users in the future – hopefully. The problem I’m having is with getting my existing subscribed users – who are the level #0 users – to be able to view the restricted pages I’ve setup for level #0 users. It seems that the SUBSCRIBE process through MailChimp and the REGISTER process through s2Member are 2 seperate processes.

What I’m hoping for is that when a user subscribes via the MailChimp embedded form that they are also automatically registered and able to access the restricted level #0 pages WITHOUT going through a login process.

Some background info:

1. I’m using the free s2Member framework
2. My existing level #0 users have subscribed to my site via a MailChimp embedded form
3. I am using the KC S2M+MC plugin to sync my MailChimp list with s2Member
4. My site is http://cadsmarter.com

Thanks for any advice
Regards
Paul
