Hello,
I would suggest that PDFreader.com encourage to free software devolopers of pdf readers to translate his web pages. I think it is important and I think that you think it too. It could be a very big step in the popularization of the free PDF readers. I asked it to PDF Sumatra
and I think that he (and others) could accept with a bit of help (web developers, facilities, hosting, tips, ...)
I think it is a good idea for the campaign. What do you think about that? It shouldn't be very diffficult and sure that you have a very wide experience translating web pages for borrowing help.
