One of the new features on Slingo.com is the "Locator". This allows you to see what game your friends are in and allow you to follow them in. Being logged in and active on the website is key to letting this to work correctly. If you have not been active on the website for about half an hour, the system will log you out automatically. Just sign in next time you come to the site and browse like normal.
This also helps us keep up to date information on your contests, tournaments, and rank points as you move throughout the site.
