Hi Alex.

That is very impressive work, indeed. I am afraid that I not familiar with editing in Wikisource, and don't know if its community is large, but if you like you can post an announcement on the pt-Wikipedia Esplanada. http://pt.wikipedia.org/wiki/Wikipedia:Esplanada/geral and attract more editors (the mailing list is not very active). I can provide a translation into portuguese there.

Best of luck!
