Yes you can! When you have completed all of the sections in your development settings and your profile progress is 100%, you'll be presented with a 'Go Live' button.
Click this and you'll be given the option to either:
- Go Live & Publish
- Go Live
Clicking 'Go Live' allows you to take reservations but not have your development on the Yourkeys website.
If your development is already published and you want to remove it from the listings, simply untick the 'Show development in listing' check box and hey presto, it will be removed!
