1. It's simple as you say, I lock this one another starts so why bother. Why? There is obviously some interest otherwise the thread would have a short life and die a natural death as do the vast majority of threads herein.
As a moderator I am constantly surprised at some of the threads that take off and others that perhaps should do, but don't. <img src="confused.gif" border="0">
2. It's also a simple matter to just ignore them, completely, unless you feel compelled to participate, in which event don't ask me to close it for this reason or that if it goes in a direction that doesn't suit your personal views. Yours are as valid as anyones as long as they are presented according to the rules.
3. If you are concerned that somehow misinformation on a subject is being propagated then trust your fellow PPRuNers and believe me they are very very quick to do so, to correct this. Single sided arguments on any subject rarely last long, ask mrs woomera
4. None of the Woomeras were directly or even indirectly involved then or now, our ONLY task is to keep it clean.
As always around here, it's your choice.
