Invisible buddy bookmarklet
Have any buddies on you AIM list that set their status to invisible? If you use iChat in OSX 10.4 you can’t get them to show up in your list. (iChat in 10.5 lets you view “offline buddies” so this isn’t a problem.) Drag the bookmarklet below to your bookmark bar.
(This won’t work if you’re using an RSS reader. Go to the posting to do it.)
Now click the bookmarklet and enter the screenname to open a chat window.
