From today Google Labs has been enabled for mail.wbs. Google Labs allows you to try out some experimental new features in Google mail. You can access labs by clicking on the green icon towards the top right corner of your email screen or by clicking Settings > Labs. It might take a few days for the icon to appear.

If you're going to brave the Labs world, it's important to keep in mind that these features may disappear or break at any time. Labs features that work well will graduate and become regular features. If (when) you have a problem with a Google labs feature log in using http://mail.google.com/a/mail.wbs.ac.uk?labs=0 to disable labs temporarily. Disable any Labs features that you have added until the problem is resolved. It is valuable to Google if you provide feedback by visiting the Labs Feedback Group.
