I've been looking all over for something that shows me when my contacts open a conversationwindow with me and when they close em down. I've seen my friend using it but he can't recall where to find it.

Please help someone

There's the script, but you cannot always be 100% sure for it. The script notifies you when new session is opened. That can be when user changes display picture, opens conversation window and many other events, which seriously affect the behavior of the script.

Thank you, I will try it out
