So far I've found community builder & cbsubs awesome.

I provide training & coaching material to paid subscribers and need to make content available whether through published articles or downloads dependant on a period of time from the subscription date.

So if someone subscribes to plan A which comprises of a number of modules (articles) they only see subsequent modules a number of days, weeks or months after the date they subscribed to that plan.

Do you know how I can achieve this?
