I have seen it on other forum softwares where you can have the rebuild option remove all posts and topics that aren't tied to the database (posts that aren't tied to a topic and topics that aren't tied to a post). This would be useful to add to IPB as my database has about 9,000 posts in it currently which aren't being used by any of the topics in my database and it's just wasting space against my database quota; and I'm not sorting through over 100,000 posts to find out which ones those might be.

Wow, I could have sworn this was in there...really surprised it's not. :o

You might be interested in this post then in the customer IP.Board area. :)
