The game now provides an Export Player Data feature.
Using the .json file that is exported (by using the hamburger menu, then going to 'Settings', 'Account', 'Export Player Data'), you can upload this file and share the link with other users.
To do this, I recommend renaming the file to your discord or account name.
The file exported will be ExportedPlayerData_YYYY-MM-DD_HH-mm-ss.json, so for example you would change this to Bumblebee.json (my account name).
Once that's done, visit http://frontiers.cubedweb.net/
Instructions are available on the site too.
Once you're there, go to the "Hangars" page, and drag and drop the .json file on to the site.
Your hangar will be added to the list (with some stats).
Click on your hangar in the list to view it (or view other people's hangars).
Once you've clicked on your Hangar, you can share the URL with others (if you're looking for advice on your units for example).
If you have any issues, comments, or questions, please reach out directly - all contact information is on the home page.
