Yep, I can code some things but PayPal code tends to be a bit picky from my experience. They don’t mind doing some manual work, the plugin takes away most of the manual work they are doing now.
Curious, is there a volunteer schedule in the plugin? IE: So that volunteers can be signed up for hourly time slots and it blocks out the schedule to show whats open and whats taken. I found another plugin for it but noticed you have a spot for volunteer hours and donations made for a user so I wondered if the schedule was also included.
