That was fast!  Thanks to both of you for posting the books to the article and clearing the article's notability tag. 63 hits on Google Print search of phpBB: http://books.google.com/books?q=phpBB&btnG;=Search+Books&as;_brr=0  Perhaps (1) extensive documentation is a feature worthy of mention and citation under Features section?  That, and (2) wide deployment and (3) broad community of active developers, are features I look for when evaluating Open Source software for enterprise applications.  Can these three features be mentioned, with verifiable citations to secondary sources?
