I agree with most of what's been posted, but I wouldn't count on getting a good version ChatLog for XP (I'm being a little pessimistic, but useful programs tend to not get made these days). Also, I don't think too much emphasis should be placed on how original or how good a level should be, although innovations and great eye candy would be a definite plus.

As for the Team Battle levels, I'm hoping the levels are well-made, seeing as it would be a shame if the gametype couldn't be played because of glitches. Personally, I think the method I created (see Team Battle in my signature, and thanks to FireSworD for his find) is the best overall method for creating TB levels since I haven't seen any major problems with it so far and it allows the warp targets in the playing area to be placed anywhere with no problem. The method could be simplified for certain levels, but I wouldn't recommend it unless you knew what you were doing doing. I might post a clearer version of my method if anyone asks. I wouldn't mind helping with the TB levels by the way.

From what I can tell, the next JJ2WC looks great already. Good luck with the tournaments!
