Of course I don't resent taking the time to reply, if I did why would I bother? Whether a person is putting out a personal request for information or merely starting a conversation, I personally think it's strange to show no further interest once others have entered into the conversation or exchange.
I wasn't being passive/aggressive, I was being cheeky and sarcastic. If that's the same thing in your book then sorry, but it wasn't really mallicious. I'm not the first person to comment on the fact that people do this, I just felt like saying it that's all. I have seen lots of people write long and helpful replies on other threads, and have done so myself, and then not even know whether it has been of any help, or been read even does sometimes make one wonder if was worth trying to be helpful.
The fact that I said it in a non aggressive way with a winky face at the end was meant to be friendly but make a point.
Your own response, juxtaposed by the fact that others have expressed what I have in the past, just go to show there are split camps on how people like to interact on forums. Let's just leave it at that and agree to differ shall we?
