@Chights47,
This is the way I meant the multiple letters...say someone posts the word madam...In your word you can use the m, a, or d in yours...so if you were to post a word with 4 m's, 3 a's, 1 d it doesn't matter...So from the word madam...
if I posted Miriam...It would work, If I posted Dag-nab it would work, or admits...it still works, it which I only used 1 m, 1 a, and 1 d...
And in your word you can repeat letters so long as it is 6 letters, and your using 3, but using any combination of the same 3 letters, so your only using 3 of the 6...
