Not only was
ScottC exactly correct in taking these actions (which were obviously in the best interest of FlyerTalk), but his explanations on each of the threads he closed were extremely clear, complete and polite.
I am, as a matter of principle, opposed to
unnecessary meddling on the part of moderators, but in this instance, the only thing I can say is,
"Good job, ScottC".
I would suspect that the OMNI moderators have their hands so full with
really necessary meddling,

that they don't have time for the unnecessary variety. I don't read a lot of OMNI, but from what I have seen, the moderators efforts have been either seamless and invisible (which is terrific) or extremely logically and clearly explained.
Congrats!
