Note to readers

Due to a misplaced mouse-click, a largely unfinished article draft was accidentally posted to the blog, long enough to appear on both the MEI homepage and the Twitter feed. My apologies; the "Save" and "Publish" buttons are next to each other. The post, on coins from the Sultanate of Kilwa found in northern Australia, will appear in a few days when it is ready. My apologies for any confusion. Consider it a preview of coming attractions.
