I tend to agree with Toorak. Still it is probably better, on balance, to have quality rather than quantity type of posts. I think it is fair to say some threads are more inclusive than others and people will withdraw quickly from posting rather than feel brow beaten.
Some folk may be out on the town, at parties/celebrations, bbqs, dining with friends/family, away for the weekend and forsaking AB. It is nice to know there is life away from here :) Of course some who were up for banter no longer post - for one reason or another. Such is life.
