Concerning the 9th player, the Rookie:
If a player qualifies for all but the <120 cards prerequisite can he still be recruited as a rookie?
How much time is allotted to the recruiting of Rookies?
Is it absolutely essential that the rookie sends the mentioned screencaps to the general?
Warmaster, I'm sure the general wouldn't mind you having more, but that's not what it's about
And yes, no screens, no proof. Anyone can say they fit the requirements, and people who are eager to join would be motivated to lie if that's what it takes to be in the war. If you fit the requirements, then you can bring up proof.
