Multiple Skype instances

So today i needed to open a second Skype instance to talk to my father...

After digging the StackExchange forums i've found a interesting way to do that. After just pasting the command line into my shell I've discovered (or remembered) that my Skype was installed using the fantastic package manager homebrew. The cask extension uses as default directory structure "/opt/homebrew-cask/Caskroom/skype/latest/Skype.app", resulting in a strange error which it does not show anything related to a wrong directory structure.

To fix this issue and improving it by making it open any number of Skype instances i've ended with bash script called new-skype.
