Group for Coaches
It is possible to create a private Category for the athletes you coach, so that only the group members you select can access the category.
If you are a coach and would like a special Category, just send me a message with the Group name you would like.
When new users want to join the group, they need to select the "Groups" icon, click the desired group and then choose "request access". The group moderator can then accept/refuse the new member.
