When you first join the FA community, FA opens an account with your parameters. Once you receive your first receiver, you should link your receiver to your personal account. If you decide to add a second or third receiver, they should be linked to your account also so that all your stats are combined. Your account dashboard should be the combination of all your receivers. To view a specific receiver stats, you select from your list
We already support having multiple ADS-B receivers linked to one account.
To see aggregate user-level stats, you can browse https://flightaware.com/adsb/stats/ (user stats). Most users don’t have more than 1 site but we realize there are users that do. We can consider aggregate stats on the My ADS-B page in the future. Thanks for your idea.
