If you and the founder of a FlightCrew, what does the “Dispatcher” check box do?
In other news, if you have a Raspberry PI running PiAware please consider joining my group:
RasPI_PiAware_Loggers at flightaware.com/flightcrew/4415028/1469
Currently RasPI_PiAware_Loggers is the number one ranked reporting group with ~300 active members. 
“Dispatcher” is relevant only when Flight Crews are used for pilot flight planning.
Thanks for the reply 
How do you delete unaccepted invites?
You may not be able to. One thing FA does (that I think is smart) is limit a request to join a group to one email. I like that because it reduces unwanted email traffic.
WOW!!!
Fast forward three years and the count for the
RasPI_PiAware_Loggers Flightcrew is 2,492.
I never imagined it would be this popular when it was created.
