I am a member of SaabCentral, another forum that ran phpBB.
Yesterday it got hacked into, and they ended up changing the forum software. Some info here: http://www.saabcentral.com/forums/announcement.php?f=16
Anyway apparently the password database can be hacked into easily and the whole forum ****ed over.
much more info here: http://www.webmasterworld.com/forum103/246.htm
Anyway, just some info I've heard through the grapevine...
