Stellar Support Services

I love the Paid Members Subscriptions plugin and it does everything that it says it does.
The support has been stellar!
I would like to see an added feature whereby an unregistered guest could browse at let’s say three articles in one month without subscribing and then be obligated to subscribe if they want to see more.
Great plugin! Very useful now and in the future when I believe less and less web content will be available for free.
