How is my Ranking worked out?
Everyone starts on a ranking of 1500. When you play a game, each players rating is taken into consideration, and you earn more by beating players of higher rankings. It is based off the ELO system for chess players.
Why is there a draw column?
Currently we have no time limits or ways to cause draws. However this may change if the League expands sufficiently.
Is there a maximum number of games I can play?
At the moment no. As long as you can find a League opponent you can keep adding results.
Can I cancel the Ring-bearer's skirmish in this format?
Popular consesus has us using the standard rules that existed at the time. Therefore it is possible to cancel a skirmish with Frodo (EDIT:
or Sam 
)
