Maybe you could, as a group, create more signs than thumbs up or down. We need some sort of smillie that covers 'sarcastic answer'. Sarcasm doesn't translate well in writing. (Has smilie got one or two 'l's?
Lynn - your idea is good. I have often felt the need to reassure a poster but can't think of anything to say. A nice little wave in their direction saying 'I'm here' would be nice.
I don't think it's a good idea. It would be quite upsetting to get a lot of red arrows, and also it can be quite cliquey here sometimes. Newcomers are sometimes quite ignored.
No thumbs up or down. R&S and News would be awash with them. The system is Ok as it is, when anyone wants to show their displeasure/pleasure at a post they usually say so.
