All pending requests to be added to the mba blog lists have been processed. If you are not appearing, you might want to check and see if your feed is valid. Remember, blogspot, wordpress.com, and most RSS 2.0 formats are supported. Feedburner and other aggregates are not supported and I will not add them.
Also, if your content is stale, only very loosely MBA-related, or appears that it exists only to support referral links, you are unlikely to be added.
