Was really pleased when i found there was a pdf version of the docs,
it seems the link isn't working.
is there another link to the pdf.
I am guessing you clicked on the "PDF version" link from this page or a child-page: http://learn.adobe.com/wiki/display/lccs/LiveCycle+Collaboration+Service
It doesn't work for me either.
You can find a PDF version of the docs in the SDK payload: \docs\LCCS_Developer_Guide.pdf.
I will e-mail our Learning Resources Team to see what they can do about the broken link.
Hope that helps.
Thanks for pointing out this broken link,
