Screensharing has been a hit for Skype in the Mac world with Skype 2.8 for Mac.

Now the concept is available in the Windows world with the beta version of Skype 4.1 for Windows.

Peter Parkes announced the new news on the main blog.

Peter explained: "Have you ever tried to help a friend with their computer? Or take a colleague through a presentation? Or help a friend with their essay? Or show off a killer move in a game? Well, screensharing in Skype makes doing things like that super-easy. Just click the Share menu in the conversation area of the Skype window."

With this beta, you can share your screen with any other Skype user on Windows, Mac or Linux. You can share your whole screen, or just a selection, and best of all, it's totally free.

Peter notes that Skype has "added birthday reminders, and you'll also be able to send contacts to other Skype users. For those of you who missed these features in the last version, they're back .

In addition, 4.1 Beta lets you import contacts from a range of other services including Gmail, Windows Live Hotmail, Yahoo! and AOL.

You can download the beta, and in return, Skype is asking for feedback about the new features, and let us know if you spot anything which doesn't work as expected. You can fill out feedback survey .

Just keep sharing on the screen and in the survey. The input will help improve your work as well as future versions of Skype. It's all about sharing and caring.
