New modules:

• Comment closer - configured to close comments on nodes older than three months. This saves the hassle of worrying about spammers posting to old threads.
• Fastoggle - Adds a few AJAXified administration functions to the site.
• Advanced Forums - Makes the forums purtier.

The forums look better than I expected. I put up a poll to see if anyone wants to migrate back to Drupal.

I had some trouble setting up the forum topics. The list of forum topics is taken from a taxonomy vocabulary. Specifically, it was using the one that I had converted into a tagging system. Since the old vocabulary was vid=1 and the new one is vid=5, I had to run these commands to get it to work:

mysql> update vocabulary set module = 'taxonomy' where vid=1;
mysql> update vocabulary set module = 'forum' where vid=4;
mysql> update vocabulary_node_types set vid=4 where type='forum';
mysql> update variable set value='i:4;' where name='forum_nav_vocabulary';

And it still didn't work because forum_nav_vocabulary was cached as 'i:1' (the i meaning integer rather than 's' for string), so I had to run:

mysql> delete from cache;
