galpal: when you resign that game you will have finished all your games in the tournament .. the tournament itself hasnt finished yet though so you would have to wait for that until you are 'released'

when you resign you wont be able to win the tournament or continue to a next round, so you can ask fencer (politely) in a pm to manually remove you from the tournament so you can join another tournament

(if there is a possibility to move on to a next round or win the tournament, then i dont think you can be removed)
