As a club administrator, you can track volunteer hours, per member.
You first need the members list. This comes either from the registration process or you can enter it by hand. If some members prefer to register with printed forms, you can enter their information and complete the members list that way.
Login as the club administrator and go to the Preferences/Volunteers. You will see the list of all members and their current volunteer hours.
To find one particular member, use the browser's "find" function, usuall CTRL+F. Once found, click the "More..." button - this will show you all the volunteer hours entries for the season, for that member and you can add more.
All these separate entries are summed up for each member, so you can always see the total.
