I've just put, what I think, are the finishing touches to the phpBB module for Geeklog. Head over to our Plug-ins
[*1] page to get it. Please note that this is not a full-fledge plugin yet but the directions should be sufficient for you to use it on a production site now.
Correctly reports total number of users
links to Geeklogs user profile where necessary
Login/logout links point to Geeklog's
Fixed bug that would allow phpBB session to expire when still logged in from Geeklog
Added phpBB credit to bottom
