(a) How does R' Shmuel bar Nachmeini learn out that future generations should read the megillah? Since he uses possuk "Ka'Yamim..." to teach the extra 2 days, he no longer can use that possuk. And if it were written explictly in Megillah that future generations should read, why then would Rav Sh'man bar Aba need to use possuk "Ka'Yamim to teach"

(b) Who are R' Eliezer b' Rebbi Yossi and R Menachem b Rebbi Yossi. Did they also write Stam Mishna's and are they R' Akiva's students? Could you clarify this?

I hope you don't mind me asking questions. I am very diligent and am reading all your material and go slow and absorb everything you write down. The only way to learn is to ask. And it's not easy asking local Rabbis' either because they aren't learning subject and it takes time for them just to learn daf well to see what's going on or time requirements, but I know that you are concentrating on the daf yomi. I want to send in a donation, do you take credit card?

Thanks again.
