As a Gmail convert, you have probably already messed around in your settings to optimize your email experience, and no doubt you've come here for helpful Gmail tips, like how the period in Gmail accounts can go basically anywhere in your email address, but are you aware of Gmail Labs?
To hear what I like about Gmail Labs, just read more. The Labs contain rotating, experimental Gmail features that you can be the first to try out — I have a few applied that I love, like adding profile photos in Gchat and the feature that applies random quotes as signatures to your emails.
Get to Labs either by going into your Gmail Settings or in the little green beaker on the top margin of the page.
Not only is it a sneak peek into features those Google kids are working on, but they enhance an already great email system!
