I may not have joined this fourm if I had not "had" to because of the downloads.
Really look at your goals and your barriers.
Goal: Get people to look at the forum, maybe even join it
Goal: Get people to download the FAQ.
Goal: Reward members
Barriers: having to sign up and get an account before downloading.
Suggestions:
* Leave the password on the downloads section
* Put a note IN the downloads section that says "Password available in our fourm"
* Leave at least one forum viewable to non-members (all might be now, not sure) in that forum have the stickied "password" thread with the password right in the thread.
Varients:
* Put the FAQ available for download and community stuff in the passworded downloads section
* if you do the above you could keep the existing password scheme (just put a note on the page to join the forum for the PW) or use the above suggested method.
Anyways I'm new here and thats just a few thoughts off the top of my head
