I'm looking for a way to use paypal to add recurring membership dues to a wordpress site. I do not need/want the functionality to add paywall to content, and don't need to have the members create wordpress accounts on the site. I'm merely looking for a way to facilitate the transactions.
Is there a plugin that offers this sort of thing? Bonus points if it's a free plugin, or one with a one-time expense involved. This is for a nonprofit site, whose organization has a tiny budget.
