If you've created a LifeDesk but decided it's not the system for you, we request that you delete your site. It costs time and money to keep each LifeDesk running and up-to-date. So if you know you're not going to use it, it's best to get rid of it.
To delete your LifeDesk, simply log into your LifeDesk owner account, then click on Administration in the left sidebar. At the bottom of the Administration page, there's a "Delete Your LifeDesk" link in the Manage Your LifeDesk section.
