Explore Calendar Labs
Google Labs are where all the cool experiments take place; well, not all of them, but many of them. There are Google Labs for the Google Apps including Google Calendar. Google Labs are experimentsand not always the most stableand there's no guarantee the features in Labs will be sticking around forever. You can enable Labs for your domain in the Domain Settings of Google Apps and then you can explore these extra doodads for each of the Google Apps. You'll know you're messing with Google Labs when you see a tiny green beaker in your menu bar.
