iChat for Mac has a great feature: when a buddy comes online you can choose for your computer to speak the words: "Your buddy is now online". As the default voice for Mac 'Victoria' is pleasant, it's not an annoyance. It would be great to have this alert option added to the Skype for Mac.

The feature is most certainly being worked upon, the UI already have the settings for this, but they're disabled at the moment, which probably means that there was a problem with the feature at the time of the release, but hopefully it should be in the next release :wink:
