Okay, so, the SMF team just nixed the smf-drupal integration module, like, last Friday. It was taken down and no recourse was given. The Simple Machines team does not want to waste time making a compliant bridge for any gpled cms, not even Joomla (which also recently moved from SMF to phpBB), and is hostile to the idea of 'unifying' two sites, as they believe it will dilute their license.
* Drupal and Joomla are Content Management Systems (CMSes). SMF - Simple Machines Forum, is the CMS that 'runs' this forum. Wordpress, Livejournal and Blogspot also run their own CMSes, which run those sites (and in the case of Wordpress, many, many others). A wiki is another type of CMS - Wikipedia and Elluiki run off of Mediawiki.
I want to move to a CMS for the entire site, so that members can set up their own blogs, and so that the front page is more powerful and less fugly. Since Wordpress is mostly a single-user blog system, the options were Joomla and Drupal and after trying and failing to do what should have been stupid-simple in Joomla... going with Drupal.
So, I obviously want to integrate it with the forum, but I can't. Straw + Camel = broken back.
So, I want to move the forums to PHPBB3. The security record is -significantly- better than phpbb2, and has a lot of features that SMF and even SMF 2 will lack. The most important ones either have a module available, are simple to rewrite, or are things I want to completely redesign anyway.
The move is probably going to happen some time after I move the front page to Drupal (Which will be painless), but moving to PHPBB3 will take nearly as long as upgrading to SMF 2 will (ie, several hours). It won't happen until I've tested the process and made things work appropriately on my own machine (including a new triple-column layout) - so don't worry about things getting broken for good.
I'm posting this here as a forewarning and to gather vitriol and opinions. : )
