I have never understood why people have to make a show of leaving an internet forum. Either you stay or you go, but flouncing (which is the term for it) is more of a "you guys don't play nice so I'm taking my toys and going home" thing, where it is expected that everyone will feel bad and beg you to stay.
Either stay or go. Sad to see you go, but it happens. Glad to see you stay if you do. Either way, I wish you well.
