Select one of your boats then select “View all signups”. Next to an event description you will see a envelope. Clicking on that will bring up a dialog box from there you can type in your message. Be creative, dock code got changed, Joe has beer. traffic will be bad in the park, whatever information you need to send. When you click on “Send” the system will send an email to just the crew signed up for that event. No more spamming your entire crew list to tell them you are going to be 10 min late.
