My two pennies worth:. .. .IMO threads should be treated in the same way as normal conversation in that they very often veer away from the original topic and it is up to the instigator, in this case the original poster, to police the thread if they feel that the thread has been needlessly hijacked!. .. .An example.. .. .If I start a thread on say, "Landing a Katana in a strong cross wind" and the thread starts to take in PA28s, C172a etc then that is fine. Let's say that Whirlygirl ( <img border="0" title="" alt="[Wink]" src="wink.gif" /> ) pitches in with how the approach is made in a Magimix, then fair do's... . .However, let's say that she completely hijacks the thread and starts banging on about how she saw Russel Crowe in his latest blockbuster getting out of a Puma during the opening credits and wasn't it cool, then, I as the originator of the thread could POLITELY ask her to get back on subject.. .. .Self moderation....see? <img border="0" title="" alt="[Smile]" src="smile.gif" /> . .. .I see moderation as a failure of the forum participants to be sensible and considerate of others. This is a polite forum, which is great to see as so many degenerate into slagging matches and only then, if anyone starts getting too arsey with another poster/s should moderation come into effect.. .. .Whirlybird - just using you to illustrate a point... <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> . .. .Perhaps Big Red L could finish this thread off with his reply and then we can get back to the important stuff - chewing the fat about aircraft.
