For our Discord server, it's important that we use our real names, and not just a silly or cryptic username that we might use in some other anonymous forum. We're going to see each other on the courts and use real names, so we should continue that online.
To updated your "nickname" on the server, follow the process below based on the device you're using Discord on.
Tap the menu icon in the top left corner (three horizontal lines). You should now be able to see the list of channels, and
Long-press on the GPC server icon, then select More Options.
Scroll down and select Edit Server Profile.
Finally you can change your name in the NICKNAME field.
