In Skype Conversation Settings, there is an option to "Notify me only if these words are mentioned" ("Enter single words separated by spaces").
However, this does not work for me if I enter
(*), the skype character sequence for the Star emoticon.
How do I put notification alert on an emoticon in Skype?
Staff members notify us about important events on a skype chat where there is a flood of irrelevant information also going, so it would matter. (Unfortunately we couldn't yet agree on a more viable announcement alternative.)
