So where does that leave me, other than tired and frustrated?
Well, what are the options?
Drupal
No decent forum options! vBulletin integration is stuck at Drupal 5.x and Drupal's own forum code is unworthy.
Drupal's blogging options aren't the best.
The
Drupal Blog Module provides member blogs under Drupal. This is better than what is provided under either Joomla or WordPress.
Drupal probably has the best community building options, but not the easiest.
Joomla
Joomla has weak integrations to vBulletin. If I chose Joomla I would probably downgrade to Fireboard instead of vBulletin -- just for the sake of tight integration with Community Builder.
Joomla can integrate with Wordpress or replace it with MyBlog.
Joomla has the easiest community building options.
Joomla can have member blogs with the addition of MyBlog or IDoBlog.
WordPress
This has the best forum integration with vBulletin, but leaves me with severely limited community building options.
The "Complete Wordpress/vBulletin Bridge" does not support Wordpress-Mu, so member blogs would be limited to vBBlog.
Summary
WordPress probably isn't going to work well as a primary CMS.
Drupal isn't going to work as a forum.
Joomla isn't the best at anything, but overall it appears to be the best option for
everything.
