I suggest (for the time being) that you set all userids at that site
 to receive
distributions with the following option
 
SET listname FULLHDR FOR *@*site
 
Then have the user mail you the distribution of one of the newly
generated list postings (or maybe even the notification of the SET)
that they received: it should have sufficient info to track down the
subscriber address.
 
You may then re-set the headers to a more terse format
 
SET listname SHORTB FOR *@*site

Post the FAQ right before the daily (?) distribution.   This should
help ensure that you are the last digestified entry.  Maybe you'll
need to tweak the daily-distribution time-of-day?
 
Or don't post the FAQ, but store it in the filelist and make reference
to it from time to time, and include instructions on how to get it
in your WELCOME file.
 
As far as your number 3), how about setting those users to DIGEST?
