For a long time, I managed to use a feature in
GAIM Pidgin that was known as the Buddy Pounce. Its described as:
When you set a pounce on someone, you can choose from a number of events, such as sign on or status change, and then you choose from a number of actions. These actions include everything from playing a sound (like an alert would do) to sending a message to the person, to executing a command. This action will occur the next time pidgin detects the event, i.e. the next time the person in your buddy list who you have pounced signs on.
I hardly use Pidgin any longer. I use its cousin, AdiumX, on the Mac (work IM? There’s skype and IRC). To do it in Adium, you have to right click on the contact, select Get Info, then set up a pounce in the Events tab.
Great, now you can hear when someone you care about signs in… With reference to ticket#921. Not very intuitive, but maybe I was seasoned to look for “Buddy Pounce”.
