In the past week I have been looking at Drupal for a project I am working on.
The main reservation I had about Drupal was the forums module. Looking at the discussion on the Drupal home site I was not the only one. Most people seem to want a fourm that looks like phpBB, mainly because that is what existing users seem to be used to.
There are two ways that go someway to achieving this goal. The first is to alter the Drupal forums to look like phpBB. I found various pointers to this but not what I considered a complete solution. The second method is to set up both Drupal and phpBB and use a Drupal module to handle the login’s for both and to exchange the user data. It also requires the use of mon_rewrite to direct the user to the correct place for logging in. This seems to have the unfortunate side effect that I at least cannot get in to the phpBB administration panel. 
I can get in if I suspend the mod_rewrite rules but the effectively breaks the site for other users, not a problem while testing but once it goes live it can’t happen.
This morning I was about to buy two books on Drupal and phpBb from Amazon when the recommendations in the checkout mentioned Joomla. I came to a full stop on the check out and found the Joomla website. There seem to be several options that work with phpBB and I am now setting up and install to evaluate.
Any one out there have any opinions on Joomla?
