Sorry all, have not been following this thread for a few days as I have been pulled in too many different directions...
1) On the detfault directories... It does assume by default that phpBB2 is installed in a root directory 'forum' on your website (i.e. '
www.mysite.com/forum
') you can modify this to work with any subdirectory within your website. It currently does not have any cross-site or cross-database capability. I know Martijn wants to add cross-database capability and the other shouldn't be too hard either (but let me check first... as php files are included from that directory listed... need to check on how php includes or does not include files on different servers... that allows us to read the setup variables from phpBB like table prefix, etc.). For what its worth (FWIW) Martijn has his Joomla installed in a root directory and I have mine in a subdirectory so both locations for Joomla should work fine.
2) Hope to get time to work on the control panel in the next week or so... Our internal alpha can ID the users ready to import/export but it just doesn't import/export them yet... so pretty close just need time.
3) Have not tested with phpBB 2.0.19 but did check their sessions.php file... the modification mentioned in the README file still works as I think the files are the same from 2.0.18 (tested) and 2.0.19.
4) Single singon/login should already work in 1.1 beta (actually 1.0.1 beta). There should not be a difference whether you login from URL or through wrapper... It you have the plugin installed, published, and the user has a phpbbID that is valid it should start a phpBB session at the same time the CB session is started. So with the exception of timeouts you should be logged in (via database table)... So if you see cases where this is setup correctly and it still does not start the session then let me know... My site currently uses a URL link and appears to be working.
Hopefully my 'distractions' should die down in the next day or so... so with luck I may be able to get the next beta ready early next week... keep your fingers crossed.
Thanks for all of the feedback.
