You or your members can add a member's birthday to their profile in the system. Add a birthday by going to the member's profile and select 'Edit info'. 

On the next page select the Birthday field and add the member's birthday. 

Adding a birthday will let you know when a member's birthday is coming up.  The system will send you an email letting you know the members that have birthdays in the coming month. 

Members can go to their MY Info tab and add or update their birthday.
