no comment?!?

Yes it hes happened to mee too, but I don't mind, maby the other people were just their friends, or maby they allready abandoned the discussion or chose a best answer

I'm sure it has happened to me before. I don't usually go back and check the discussion though unless someone has replied to my post. We're not supposed to leave a comment for everyone, but I think that guideline is more for when people just say, thank you for commenting, or thanks for the answer. Stuff like that. One time when I was trying to figure out who to give a best response to, I realized of all the 40 responses to my discussion, there were only two I had not commented on. I had not consciously done that, but as I looked them over, I realized they were just two that I didn't know how to answer, or couldn't add anything to their answer. I don't think people do it on purpose, truthfully I don't think it even occurs to them how many they comment on and how many they don't.
