I'm totally with Pat and TRex on this one. There are a huge number of words that are classed as uncommon that I know perfectly well, yet I am happy for their uncommon classification to remain (well mostly). In recent 7BM I had outpoll, purpler, replot, espies, weepie, whisperer, wispier,... All of these are probably known to most players but, except perhaps for the last two, I understand why they are classed as uncommon in Chi. Another uncommon word I used, athwart, is in the same class as aquiver, yet I wouldn't argue for its reclassification on the same basis as aquiver. Because of my background in making maps, the word replot is very common to me. Although it is probably known to most players, l well understand that the majority exposure to the word is at much lower level than mine and the uncommon classification should remain.
