Add QIS to the list of three-letter words
Howdy! Noticed just now that QIS isn't in your drop-down list of 3LW. There may be others, but I haven't noticed that yet. :)
Also the list of 2LW must be American-only, as there are number missing that are allowable in SOWPODS. Might help to mention that. One site has the UK-only 2LW shown in another colour, with a note to say why...
Thanks as always for the great tools!
