I could see myself using your service to charge monthly for access to a webapp. Do you have any plans for that, so that a user has to pay only once per month instead of each click? Apologies if that is already in place.
Subscriptions are not available yet, but they will be in a few weeks. Just to clarify, the user does not pay per click, but rather per link. If a user has already paid for a link, clicking the link a second time will forward the user to the correct content.
