Your Screencast.com Account
Jing is tied to TechSmith's Screencast.com. When you install Jing you must create a Screencast.com account associated with a valid email address (unless you already have a Screencast.com account). This becomes your "Default Account". If you have multiple Screencast.com accounts (such as for work or personal) you can associate whichever account you wish on a per-button basis.
