Skype allows you to make calls to other Skype users for free, but calls aren’t the only thing you can do with Skype. Its extensive features included IM chat with contacts, group chats, video calling, conference calling, file transfers and money transfers via PayPal.
Skype lets you import your Outlook contacts into your Skype contact list and once their imported you can easily organize them into handy groups.
A nice feature for people who don’t want to miss calls when they’re away from their computer is call forwarding. You can set your Skype account to forward calls to your landline or mobile phone so you won’t miss any calls. This is not a problem for people who have Skype on their mobile phones.
