Good but flawed

I enjoy this game but would rate it more highly if you made a few changes. The most frustrating feature of the game is that the selection of words is far too arbitrary. For example, in my most recent round the word "don" is not accepted, the word "dun" is accepted but not its plural "duns". Far too many good words which are not obscure are left out.

The other change I would like to see is a button to allow me to repeat a word Ive just entered so that I could extend it (by adding an "s" for example).
