Need a solution to a problem I've been having.
I'm working on an internal corporate site. Users can be invited to the website via email and attached to a credit card.
A user can only be attached to one card but there can be up-to 6 cards to choose from. I need a solution for being able to send multiple users invites to the website and at the same time attach them to a credit card. (Attaching them to a card happens before the invite gets sent to the user)
