Thanks for the comments everyone.
@Adarias: Thanks for posting that 'claimed' version. I'm going to keep track of it better now - it just got so many groups at once that I didn't have time to update this morning.
@Feron: I understand wanting a different template. I just think that mine is varied enough to be different and that isometric doesn't have to be limited to a certain setting or style. I believe that the sheer number of interested participants is a testament to how many people may actually want to do this. And seriously, if it comes down to there being a number of tiles that no one wants to finish, I will finish it myself with the help of friends from other communities.
As for my inactivity, I used to be pretty active. I just couldn't find the forums for a long, long time. I think I can handle a collaboration. I feel especially qualified because I have hosted complicated arts and crafts swaps online where people actually had to send physical materials to one another. Compared to that, this is rather simple.
While I'm posting, I should also say that once 12 is finished, I'm claiming #11.
