As has been stated all along, any UC not processed before transitioning to UC 2.0 would be processed via UC 2.0 itself; in fact it was necessary to have a substantial amount of content TO be processed, otherwise no one would be able to vote in order to receive submission credits. And has also been mentioned, we're still in the process of training all content reviewers on how to use the new system's considerably changed admin functions. We're also monitoring continually how content is flowing through the system, and actively tuning it to reach optimal performance.
As of this moment, I see 407 submissions "pending approval." That pool of items gets processed in the order submitted, and you can expect all 407 to be acted upon in some way before the weekend is over.
If your designs are among the 332 "in voting," get your friends to vote on flags and sails! This helps you, others who have submitted User Content, and us by helping sort what's currently in the system and get the flags and sails which are ready for the game into the game.
