By forwarding your failure notice, you've already sent it to the list in 
base64 text format, which is enough for anyone to recover the document 
:-) This list accepts bz2 attachments, so if you want to do this in the 
future then just compress it. For the archives, the attached *should* be 
your PDF recovered from base64 and then compressed.

Dave.
