Join Private Leaderboard

To join a private leaderboard, you will need the URL that the owner of the leaderboard has shared - the format will be something like program52.com/private-leaderboard/your-leaderboards-name

When you visit your specific leaderboard link, an up to 10 character join code will also be required - this is to stop random people joining if they guess your leaderboard's URL, but you e.g. want it to be private among just your friends/educational institution/workplace etc
