I don't know if this is possible, but even so - it might not work quite the way you imagine. I often have a T2w window open. So it appears that I am 'online,' when in fact, if I am trading or handling other obligations, I may not look at or refresh that T2W window for hours.
The best way to send info to a moderator is to use the 'report bad post' feature. We all get these emails in a timely manner and one of us is likely to be able to respond.
