Magic the Gathering sets

How are we supposed to know you made the answer "Alpha, Beta, and Unlimited?" I started this quiz by typing in "Alpha." That was not accepted, so okay, a lot of people don't count Alpha. So I typed Beta.. also not counted. I tried Unlimited. Then Revised. Revised was a right answer, so I knew there was something weird about the first three. Which is why I quit at that point out of frustration.

You need to add type-ins for answers. Like for the first one if you're going to keep it as one group answer, entering any ONE of the sets should be an acceptable way to get the answer. Also I didn't get this far but if you don't already you should accept "2011" for "Magic 2011", "6th Edition" or "Sixth Edition" for "Classic Sixth Edition", "5th Dawn" for "Fifth Dawn" etc. otherwise people won't have fun taking the quiz or will get upset and quit right away like I did.
