Ok, thanks for the info ^_^
(by the way, I moderate a forum as well (not an msn forum, but an anime forum XD) and I know how frustrating it is to answer/explain the same thing thousends of time, that's why a recommend to name the script the way a I did and not a "open windows convo", but I think, as you say, that a lot of people will misunderstand it all the same... Even though I still think that that's not a reason to just donīt do it)
About the x minutes for the "closed window" notify, I said, because the reasons you have already told, that even that way it wouldn`t be 100% accurate, but I think that at least it would stop the "closed windows" notify to appear once and again after many minutes from de last message... It is a improvement, no a solution ^_^ (great idea to make the user choose the time, I hadnīt thought about it!)
About the patches that delete the "user is writing a message" message, I hadnīt thought about that neither... But as I said, it was a way to make it more accurate, not a solution
