I am working on the next installment. We're going to start again with the Spanish colonization of the Greater Antilles and continue with the conquest of the Muyska. However, Bronze Age New World was never supposed to be one author's project. It isn't my sole intellectual property, but I feel I'm as good as any to be an active curator. In that spirit, I'd like to share a Word doc that I compiled in 2012 with all of the original BANW posts I could find:

There may still be some content out there in the archives of soc.what-if, which you can search here:

Anyone is allowed to contribute to this project, I hope you don't mind if I try to guide it along in a general direction I believe to be the most plausible. I'm trying to use as much of the original BANW as canon, but we've already established that some of it has to change because of new discoveries in the archaeological record and new interpretations of historical cause-and-effect.
