National Series 2011

Does anyone recall what the NS rules are for a sub? Once you take one you must stick with them? They cannot be a player already in the tournament? I'd like to get this nailed down before the weekend.

What are the rules for subs over the duration of the season? I.e, once you've played a sub at one tournament to replace a player and then play a different sub at the next tournament to replace a different player?
