Using Payplans & ES to restrict access to EB Posts?

Hi SI Team & SI Users

OK. So I have my Payplans Gateway almost finished.
And have 3 Payplan profiles linked to Easy Social Profiles:

a) A free basic profile.
b) A contributor profile.
c) And a free advanced profile.

http://www.finalbug.net/component/payplans/plan/subscribe

Lets ignore (b) for the moment.

a) goes to a ES profile called “Test Profile LEARN”
c) goes to a ES profile called “Test Profile MASTER”

I have test users called:

TP-Learn001
TP-Learn002
TP-Learn003

Lets ignore (TP-Learn002) for the moment.

My question.
How do I set this up so that:

TP-Learn001 sees the following blog post in the Group Learn FCPX

http://www.finalbug.net/blog/entry/546-fcp-x-subtitles-the-missing-webinars-01

and

TP-Learn003 sees the following blog posts in the Group Learn FCPX

http://www.finalbug.net/blog/entry/546-fcp-x-subtitles-the-missing-webinars-01
http://www.finalbug.net/blog/entry/547-fcp-x-subtitles-the-missing-webinars-02

thanks in advance

Paul
