Skype users can let their friends know that they have Skype installed.
That is not a bad thing, except when people you hardly know start sending you inane “skype me” emails via the Skype website.
I know it’s not Skype’s fault that people are abusing their system, but they really should consider putting in some form of warning eg. please do not abuse this service by sending messages to people you hardly even know
Skype Spam
