The application of the rules here is pretty flexible.
(a) posts need to be reasonably polite and non-inflammatory
(b) no overt antipathy directed at any individual .. ie play the ball, not the man
(c) some technical relevance. So, for instance, this thread started off more suitable for R&N but tracked into some technical areas .. so it can stay here ..
Not too sure just what the previous two posts are driving at ?
