It maybe just me, but i keep getting "phantom" email thread notifications. I click on the link and nothing has been added. This seems to be happening when i am the the last person to have replied to the thread, and its not happening on all threads (only a couple to be honest)

i think it doesnt care if you wrote the last message or someone else, it still counts it as new. Hence the red envelope even on your own posts. i dont use the notification myself cos im here too much anyway and i get too much mail as it is!
