Today is the Summer Solstice, which means Summer's offically here - well in the Northern Hemisphere at least. This is also the longest day of the year. Wondering what to do with those extra hours of daylight? Pull up a lounge chair, break out the tequila and check out what we've been up to this week.

Yahoo! Mail goes vintage: Frustrated by not being able to to get the email address you want? We've heard you and we're doing something about it with the introduction of two new email domains: ymail.com and rocketmail.com. If "rocketmail" sounds familiar it's because it's vintage Internet. RocketMail was one of the first free webmail services in the '90s, was acquired by Yahoo! in 1997 and formed the basis of the first version of Yahoo! Mail. So, whether your style is brand spanking new (ymail.com), hip vintage (rocketmail.com) or comfortable classic (yahoo.com), head on over to http://new.mail.yahoo.com/addresses and get the email address you've always wanted.

Media Player gets foxy: Check out the latest wily addition to the Yahoo! Media Player. Through a rather clever integration with FoxyTunes you can now control all of the music inside your browser as well as outside of it. The latest version of FoxyTunes enhances any page that has music on it by automatically adding the Yahoo! Media Player to that page. This allows you to play any track on that page or even the whole page as one big playlist. The best thing is that once you start playing a web page with the new player you can instantly control it with FoxyTunes, even while surfing in other tabs or browser windows - just make sure to leave the page that's currently playing somewhere in the background. And, if you close that page, your FoxyTunes will automatically switch back to your regular media player, be it iTunes, Windows Media Player, Winamp, etc. Now that's foxy!

Smithsonian goes to the Commons: The Commons photo collection on Flickr welcomes its fourth member in the shape of the Smithsonian Institute. As you’d expect the collection is rich in history – from photos by the Institute’s First Photographer, Thomas Smillie, to portraits of Artists, Scientists and Inventors (yes even Albert Einstein makes an appearance) and People and The Post. The contemporary collections include American Celebrations and a documentary from the Smithsonian Folklife Festival. And don’t forget to check out collections from the other three members: The Library of Congress, Australia’s Powerhouse Museum and The Brooklyn Museum.
