People horsing around with a few jokey posts in the Practice Forum? Guilty, your Honor. I've done it too, just like EngrPaul and others. But if jokey comments are considered "fluff posting", then what about the hundreds of posts throughout the rest of CPF saying nothing but "+1", or with just a smilie or two and no text? Do those ones really add to the sum of human knowledge or, for that matter, humor? Don't they clog up the forum far worse than jokey comments?
Out-of-date threads and posts in the Practice Forum could easily be deleted by admin staff if bandwidth space is so crucial. That could probably even be done automatically, after a test thread had been there for say a week, or a month, or whatever is considered sufficient.
But what is almost incredible about all this is that Sasha has received a whole lot of complaints about fluff posts in the Practice Forum. What kind of saddo spends his time scouring the Practice Forum, of all places, looking for posts he can complain about to Sasha?
