There’s a catch, actually. In order to use Skype online, you’ll have to make the jump to Outlook.com. A lot fo users seem to love the service, but as a Gmail diehard, I’ll be staying put. It’s also important to know that it still is in beta, a plug-in is needed to bridge Skype and Outlook.com together, and the service rolls out in the UK today, with the US and Germany following in the “coming weeks”. Browser compatibility is the base standard, of course: the most recent versions of Internet Explorer, Chrome, and Firefox.
