Excellent idea, Mommakat, but I'd like to suggest a badge for 100 as well, and a 500 badge, and then the Grand Master of all, God help us all, reaching 1000.
It'd be a great idea for players who aren't good on the speed quizzes.
I have 100 words and stopped playing it for quite a while because it took SO long to get there, but it was a challenge and that's what FT is all about. Now I have 103 and swear every time I play that I won't ever again, lol. Mind you, it'd help if I remembered to go back for the last 5 minutes (and oh my goodness it's coming up again)
That game is as challenging as the Word Wizard 5,000. It takes forever. Not that I have that one yet.
Also a couple of badges for Quiz of the Hour? I feel sorry for it as it seems to be overlooked with badges.
