It happened again today!!..And I know that these friends of mine ARE invisible, coz mostly they go invisible..I still see them go Offline. And one time a friend pmed me while I was invisible and asked why they could see me go offline but they couldn't see my online status. It doesn't matter to me that people are invisible...but that means..when I'm invisible and when I log off, people can see that I have been online..This is so weird..
