Yes, it's thread creep, and yes, the complaint element is more appropriate to SLF... but why bin an entire thread just because a complaint appears? This is still alive, the points have been dealt with pretty well in my opinion, including by yourself, and if everyone now sticks to the topic in hand we'll be back on track.
Fair enough? A tactic I recommend is always contribute something to the topic, even if the main thrust of the reply you are writing is dealing with a tangential issue. Retains focus, and helps neutralise drift.
...and having broken that rule, can we keep this about the rebirth of Ansett, please. Debates on procedure, etc on new threads, please.
