Yeah, so there's two things:
1) We're only currently counting non-GOW BNE/classic maps.
2) The rungs currently need fixing. We need to make it so unranked players (which will be everyone) get slotted into the ladder after they play a game that counts. iL said I'm more familiar with the ladder so asked me to do it, but the ftp login info he sent me didn't work, so he tried something and I still can't get in. I apologize for the delay. Not 100% certain but I do think I can fix it quickly once I get access.
Very sorry it's taking so long! my initial assumption was that it would already rank people correctly, as long as their current ranks were null. But I think instead the code adds unraked people to the ranks correctly when they play their first game, not when their rank is null, so I think I just need to add like "|| rank = null" to the new player section of the code... and then reset everyone back to null ranks again.
