Thanks for explaining it, glatt.
DanaC, I generally don't care if other people misspell words (okay, not true, I do
care, because I'm a neurotic perfectionist when it comes to spelling, but I am not rude enough to correct them,) but in this case I was poking UG about it because he very frequently corrects other Dwellars, and goes so far as to loudly draw false conclusions about their intelligence based on their typos.
