How about this:
To play Armageddon games you'd require an account at least three years old. Then every time you play a match you bet one year from your account. If you run out of years, your account is closed, to which you open a new account - a beginner, a normal account, undecorated.
Dear Chess.com
Have you thought of creating an Armageddon option to Live Chess?
That would make a very interesting addition. I, for one, would love to try that.
