Roles can be associated with club members. Each member can only be assigned to one role so if a member has more than on role simply create a new role that covers both roles.
Click 'Add role' and you will then be able to enter the role name, whether the member associated with that roles shown in the contacts page, and a 'Sort order'. The sort order determines the position that the team appears in any list of teams.
To edit a team click on the role name.
To delete a role click on the delete icon on the right hand side of the list.
