Tip: Use Skype Without an Account
On Windows Weekly 492, Paul Thurrott shared a tip about using Skype without actually using an account. All you need to do is go to Skype.com and choose "Start a Conversation." When you do this, you'll be given a link to a chatroom that you can share with other people. The room will be there for 24 hours. It supports up to 300 people in the text chat, and up to 25 people for voice and video calling. You can also do screen sharing and file sharing, all free.
Premium features will still require an account, however. These features include calling regular phone numbers, real time translation, and the ability to return to a chat room after 24 hours.
