Calendar Invites opt-out (optional)
For ease of use, calendar-invitation emails will be sent from calendar-notification@google.com for each practice session. It's especially easy for Gmail users, but almost all calendar software can process them automatically.
Click this checkbox only if you do NOT want to receive these calendar invitations (because, for example, you do not use an electronic calendar, or you want to create your own calendar items manually). Instead, you will receive a single email with the link.
