What happens when I am away
I am aware that it is important to keep the momentum and the XP's up however I am due to go away for just over 2 weeks soon. How do I reduce the risk of sinking below the demotion zone and losing everything?
The "demotion zone" is just used to shuffle you into a different random group of strangers to compare yourself against - it doesn't mean anything. If you typically get a particular number of XP each week, you'll get back to your default "zone" fairly quickly once you come back. Your accumulated XP will still be there, your crowns will still be there. Your streak will be gone, but it's only 14 days so you'll build that back up fairly quickly.
