Interesting idea! I don't know how phpbb works, but I guess it's using mysql to store the subforums and it doesn't create a file for each subforum.
What I want to say is, that you cant use wget to download all files of the forum, since they're created dynamically, based on the database.

This means you'd have to combine wget with a recursive script and this leads here:
