Over the past 2 months I've been doing a monthly webcast series with Sirius Computer Solutions on Rational Developer for i (RDi). The format is generall 40 min deep dive on a specific topic, 10 min preview of the next month's topic, and 10 mins for Q&A.
So far we have covered an overview and a deep dive on RSE. The webcasts are being recorded and are available for playback.
The next one is this coming Friday (November 13th) and will cover the Integrated i Debugger; one of my favorite RDi topics because it's so easy to use and something I have to use often when coding RPG, COBOL, or CL 
Here are the details for the upcoming call:
