Joe's isn't working (from his program (you need an account to see links)) so I made one myself. This will be handy for another program I'm releasing soon. Anyways, simply run nbusers.exe and let it do it's thing, I suggest leaving it on overnight as it will take a LONG time to complete as it grabs every username from every post on every page of every topic of the first 7 pages of every board in the Neoboards.

When it's finished, it will generate a text file called "users.txt" in the same folder from which it was ran. Duplicates will already be removed.
