1) The problem → Creating a option for limited number one-time-payment membership with an associated feedback attribute that shows the number of memberships which are still available, or a message when none is available

2) Why is this important → Create an early adopter user base, or limited membership availability. It will help in the early stages of market validation of a product

3) What's your plan B → Create a javascript function associated to a 'lifetime' type of membership and web hooks, to count the number of signup events

4) Possible solutions we could build for you → Email notification for every time a signup happens (regardless of the membership type)
