How so? I get the impression when I visit those forums that nobody knows anybody, haha...I hardly ever see anybody acknowledge another member there...but I could just be missing it, as I'm not exactly on the lookout.

That's correct, i've been posting there for about a year now and not ONE person has even quoted me or thanked me or even noticed my posts! There is an inner crowd in these forums, SP especially (probably don't realise it because the forum is so large!).
