Stealth Settings for Skype

For a very long time, I have been dying to see the Invisible Mode applied selectively.

There are many times, or perhaps daily, when I want to be Invisible only to certain Contacts, or just one Contact, but not to everyone else.

This feature is available in various Instant Messengers, such as the Stealth Settings (for individual Contacts) in the Yahoo Messenger.

But there is no such setting in Skype as of now. There is a workaround however.

I simply block the contacts when I don't want to talk to them, then just unblock them when I want to.  If you block a contact, you will appear as offline to them regardless of the status you selected.  They will also receive no notification or warnings when you block or unblock them.
