Is it just me but I spend what seems like hours going through all the forums and chat rooms looking for friends who are supposedly online but are not.
A follow on thought would be that could it not say on the profile where someone is when it says they are online?
Finally, a thought to those who moan about lurkers and stalkers, why not try saying hello yourselves - it can be daunting jumping in to a chat in full flood, especially when the chatters know each other and there is a lot going on that has obviously got a lot of history to it and makes no sense to the new-comer!
