Recently we consolidated a number of blogs down to a smaller number, and also brought over the original Sitewide Blog. As a result we're not getting the benefit of the fix to category duplication, and to proceed to the next step we'd like to completely clear Sitewide Blog and then regenerate it. We also want a smaller number of posts in the sitewide because it will be more efficient.
What is the best way to clear the Sitewide Blog? Just go in and clear the post and post-meta tables and then use the regenerate feature? Will this correct problems with the category duplication?
