blafferty That is very sweet of yarb. I might warn people in general not to adopt any cowboys, or let your words grow up to be cowboys, however. Jun 14, 2011
bilby Blaffertjes, on the old Wordie the words that weren't listed did not have a page as such, simply a 404-style placeholder that said "Nobody is listing xxxxxx. Why don't you?" If someone listed a word, and then unlisted that word, a page would exist but with a blank 'appears in these lists:' column. We referred to these pages as ghosts or orphans. The kindly yarb set up a place to house them which is why cowboy up appears on a list called Adoption Agency. Jun 14, 2011
