Managed to connect phpBB3 with joomla user database, may need a bit of tweaking but one way autologin works (joomla>phpBB3). Here is a demo of it up and running: http://www.oldnine.com/joomla/
. I've requested the theme located under http://www.oldnine.com/forum/
just to have some references when we're to make our own :).
I think we are ready to make some decisions so I suggest a meeting on Saturday at 8pm GMT where we select fonts, style, colours etc. Probably having it taking place in some IRC channel, just checking so you guys have time and such before deciding where and how it takes place ;).
