So, somehow a user account on ka72.com got removed, and all the tracks remain on the site, but they are no longer associated with the sailor.
The sailor has a GW60 device, with the userid "wavegear" in the device. They sail exclusively in WA waters, and uploaded tracks between 27 January 2020 and 1 January 2021.
Normally I'd not worry too much, but this user is on the leaderboard at a number of different sailing spots, and the missing user account has caused the Kingdoms pages on the site to stop functioning.
So, either I can reunite the data with a new user account, or I can delete it to get the kingdoms working again.
If you know who "Wavegear" is (or think you do) please get them to get in touch with me via dylan@ka72.com or on my mobile 0481586587 to sort it out.
