Unlike most other instant-messaging systems, Skype allows you to edit previous messages and even remove them altogether. Our Helproom Editor explains how to edit messages in Skype after you've sent them. You can download Skype for Windows 8 here.
QUESTION I was typing in a message to a friend on Skype, and noticed that some of his earlier messages had changed. How is it possible to change messages that have already been sent?
HELPROOM ANSWER Unlike most other instant-messaging systems, Skype allows you to edit previous messages and even remove them altogether. This will edit the saved message history and also change what appears on the recipient's screen.
We can't see a great deal of use for the facility, but if you're embarrassed by a spelling mistake or you've said something you later regret, you can go back and change it. Perhaps it could save you some embarrassment if you have one of those ‘whoops, wrong window' moments, but only if you catch it before the message is read.
To edit a previously typed message, just right-click (or tap and hold in the app) and select Remove Message to delete it, or Edit Message to change it. The recipient will be alerted to the change, either by a pencil icon next to the altered message or a dustbin icon and the comment ‘This message has been removed'.
