One can report only 1 battle a day - but a person can confirm from any number of OTHER players who report a battle. So the trick is to play lots of different people each day instead of just 1 - and if you do play just 1, you need to have them register a battle and you register a battle, and then you confirm each others' actions - making 2 battles per day.
Any other questions? Try the NC forum instead of the Elector's.
