After a relatively short testing period, the official version of Skype 3.0 has been released and is now available for download. If you're a Skype user, this is a must-have download. If you're not a Skype user, Skype is a chat tool that enables you to chat in the old-fashioned way via your computer keyboard or through a telephone connected to your computer. Calls through Skype are cheaper than traditional phone calls.
Skype 3 contains a number of new features. The first thing you might notice is that the interface has had a bit of a visual makeover. You can now find and enter a public chat (conference) or invite different colleagues to join you in a conversation - ideal if you need to set up a conference between people situated in different timezones.
