Is a word list for Megavocab available?

I want to add a number of ecclesiastical words to the Megavocab game (I'm a pastor). It would be a big help to be able to get a listing of all the words which are already in the game to avoid duplications. Since the words come up randomly, it's hard to know exactly what words the program come with. Also, I'd appreciate some advice on what size photos work best. Thanks for any help in this matter, and have a great Thanksgiving! pastorbk
