Well I cannot downmod comments I have already replied to. Up/downmodding does NOT mean you agree or disagree with that comment, it means you find it useful/interesting or that it has added something/contributed to the discussion
I can still down mod the comments in this thread that I have replied to.
EDIT: wait NOW I see :) I cant down the above comment. Ignore me :)
I volunteer to be downmodded and replied too :)
