|Do you ever change the rules or ranking algorithm? Why would you do this?
||Yes, we do make changes from time to time. Generally, when that happens, we notify players through our News mechanism, the blog, twitter account, etc.
We want to make sure that the PL/SQL Challenge offers the fairest, most accurate ranking of PL/SQL developers around the world. There may be, unfortunately, any number of ways that a person could try to "game" the system and unfairly boost their standings. In addition to the penalties described in the previous section on cheating, we reserve the right to:
• Change the scoring and ranking algorithms at any time; such changes may be applied retroactively in the current quarter. We guarantee, however, that the algorithm will always be applied equally to all players.
• Cancel a player's registration in the PL/SQL Challenge or disqualify a player from participation in a particular contest.
• Withdraw a prize given to a player if we determine after the fact that he or she violated any of the rules of the PL/SQL Challenge.
