I think I am straight and to the point. If I disagree with a point I am not shy to communicate it. I also try and have two way communication with other posters. When I first started threads I used to answer everyone individually, but now I am trying to control my post count I don't always, but apologise instead.
I think interacting with other posters is important and that's how I communicate on JWN.
I agree with Apogs' point about grammar, punctuation and spelling. I try and make sure my written communications are something I am not ashamed of, and I find it difficult to respect a posters message when there are a lot of errors in the post. The odd typo doesn't really bother me though.
