The Skype plugin allows you to add an icon showing user's skype status (online, offline, away, do not disturb).

Skype status is shown correctly if user has allowed his online status to be shown on the web (in the Skype privacy settings).

This icon is also the button to call profile owner via Skype (if Skype is installed on user's PC).

You can choose what profile field contains user's SkypeID and icon's position on user's photo (top left, top right, bottom left or bottom right corner).
