Serious Flaws

I like playing this game but you would hope by now they would have fixed the flaws. I entered todays "Weld of the Day" which was AMTRAK - not sure how they selected that one when they wont let you use so many other words in that category - but when I entered the word on my board I got nothing!! It didnt recognize the very word they chose as the Weld of the Day!! They regularly ignore common words that appear in standard dictionaries but since they use some obscure dictionary as their "bible" for acceptable words in this game, many of these common words are not accepted. Fix this please!!
