Followup to irc discussion on that topic: there is already anonymous mode in forums, although I only got it to work by granting forum_create and forum_write on the forum to the Unregistered Visitor and reverting a recent change to forums-security-procs like this:
tils@rbfm:/var/lib/reboot.fm/rubi/packages/forums$ cvs diff tcl/forums-security-procs.tcl
cvs diff: warning: failed to open /home/tils/.cvspass for reading: No such file or directory
