Today's round is not quite usual. The participants of the first division can register on it and to participate out of competition. This round will be some alpha-testing for this functionality, but for the next div. 2 round you can expect a stable version.

A suggestion; It will be really awesome if you guys could provide the test data, used by the system, once the competition is over and problems are put up for practice. It will greatly help those of use who just aren't able to find why our solution is failing on a certain test. :)
