If you want to help Skype celebrate its third birthday, you won't have much luck persuading it to come to the pub after work. However, you're very welcome to send it a birthday card - and if you do, you could win a speakerphone and USB internet phone from Skype's pals at US Robotics.

Your card can be a picture, photo, video, a written note... anything you like. Send your scribbles to happybirthday@skype.net, and post pictures or vids on Flickr, YouTube or any other of those clever interwebby places, and email Skype the link. The best cards will be published on the Share Skype blog, so make sure to include your Skype name.

Don't rush your masterpiece: you've got until the end of Sunday (September 3) to enter. Good luck!
