Issue 5 of Volume 2 was the last issue for August 2010 of Casefile Clues. If your subscription expired in August and you have not yet renewed, it was your last issue.
It's not still too late to renew. Current subscribers can renew their subscription here at the annual price of $17. We've got some interesting topics planned over the next several months--both from earlier articles and from reader suggestions. Email me at firstname.lastname@example.org if you need to know when your subscription expires.
And if you've chosen not to subscribe--good continued luck with your research.
