An integration for those two would be super.
Many that use Joomla would like to be able to use the phpbb board instead off the smf that all the coders like to make bridges for.
I use Joomla and i would allmost start to cry if there was an integration for phpbb3 and Joomla.
A working bridge/mod that make it possible to log in at the front page of Joomla and then your are also logged in to the board and vice versa.
Also, it souldnt matter if you register on the front page of Joomla or at the board.
