I am part of a swimming of club. There is some information that only individual members of the club or parents of individual members should see e.g. history of times, dates of birth and individual notices for the parent / member.
The coach would need to be able to log in to same form of admin interface and enter this information, selecting who sees it.
Has anyone any recommendations of any open source solutions. That could easily be customised to do this and would be very secure.
