Hi Rabbi Shimon Kessin gave a wonderful shiur on "Mashiachs arrival - is it soon How do we know" in RBS in KSY. The link of the video is on youtube at http://www.youtube.com/watch?v=CfzBQCi66Uo&feature=youtu.be for those who want to see the video again or missed it the first time. Hope all had a meaningful fast. Reuven Ashenberg
