There is no ‘group coordinator’ role so we have had to deal with this by having extra fields. I have to export the data and then write my own code to send an email to group coordinators with a list of their members. Group coordinators cannot send an email to their members from Wild Apricot. Some group coordinators do not have email and we use a buddy system. Again we cannot send an email from WA to all group coordinators that allows for this.
We have nearly 200 groups so these issues are significant.
