We'd like to try to get this going again, as we had a good start at one point before it sort of quieted down.
Please go to the forum here and read up about it. If you've claimed a level a while ago, you need to confirm you are still working on it by posting in the "Level Signup Confirmation" thread there, and then finish it! It's quite likely that there may be some level openings soon because of people not confirming their levels, so if you're still interested in doing a level or two for this, stop on by!
Remember, this is a giant collab project! Everyone's role, no matter how small, is vital to finishing this. If you think you can help out, please do so!
