From the PACER Web Site and the PACER Quarterly Newsletter:
Lasting only a few minutes each, the tutorials are a quick and fun way to learn something new about PACER or to brush up on your existing PACER skills. Starring Ms. Gavel and Mr. Sound Block, current topics include the PACER Case Locator, Digital Audio Recordings and PACER Usage History Reports.
Four videos are currently available and a fifth coming soon.
Btw, the April 2012 issue of the Pacer Quarterly Newsletter was released today (2 pages; PDF)
