I have just put up the next 4 shiurim from Hilchot Shabbat. They include an introduction to the melachot (forbidden Shabbat activities), some of the laws of saving lives on Shabbat, and a very interesting section on the importance of knowing the difference between Torah law, Rabbinic law and customs etc. Have a look at www.hilchotshabbat.blogspot.com (or click on the link at the side).
There are also a couple of new questions at www.askrabbisedley.blogspot.com – about why we are not permitted to say G-d’s four letter name as it is written, and what to do when you go to the kotel for the first time.
If you have any questions for me you can post them there (or e-mail me directly).
Enjoy. I would also welcome some more feedback from you about these sites.
