not to be mean or anything but, you probably should.. especially on the forums where it's easily misinterpreted coz there's not so much of a way to communicate it as sarcasm other than when it is very obvious.. I mean, I guess it would sound better in an actual conversation, where your tone and pitch and blah blah could clearly indicate sarcasm but when its typed, it's not really surprising that anyone reads it as either sarcastic or serious.
