A hiking group with about 500 members I belong to sends out a yearly Directory with multiple list of all members according to name, trail, name, state, etc. and has their addresses and emails, as a hard copy magazine type form.
In order to defray cost it's been suggesting to put the publication on a CD. Opponents are afraid that it would be too easy to glean the email, and snail mail address for spam purposes. I'm under the impression, it wouldn't be much easier than scanning the hard copy.
Anyway, the idea was dropped for a bit, but the club is again trying to save money. This time I suggested it been done in PDF and password protected.
Would anyone that knows better than me think this would work as well as the hard copy?
