Skype

Skype is a proprietary application for making VoIP calls and instant messaging.

Installation
Install :

Auto-launching at KDE login
For some reason, KDE cannot remember Skype in the session it saves upon log out. This is my current workaround.

To make the Skype main window (but not chat windows) go to a desktop or any other features of Window Rules with KDE, use this regular expression under Window Title in the settings window: (^[A-Za-z0-9]+\s\-\s)?Skype™(\s\d+\.\d+)?\s\(Beta\)(\sfor\sLinux)?$
