Ok, we have gone live with our new 4.0 and Buddy Press themed site. Everything is working well. The previous 3.0 install there was some sort of membership card function. When you signed up, part of your confirmation email was a .jpg that included all the pertinent info like name, gender, term of membership and type of membership. I really have no idea how this would be handled. Do any of you?
May be it was a custom plugin? There is no such functionality by default but this is possible as customization.
I could help develop this for you for v4 in a couple days. Even if you could find the v3 plugin, it almost certainly would not work with v4. Please PM me if you want to chat.
