speaking of banning, i remember getting in an argument with one of my science teachers about the backwards flushing "drop boxes" in the southern hemisphere. i was nearly banned from class. I also once was nearly banned by the old guys running a minolta forum. now that was really over nothing.
So some people have been banned here?... hmmm, i guess i'm not active enough to have noticed, and other than the occasional snarky reply i've never come across much hostility. I know that i don't know it all, and i don't expect anyone else to either.
