I can only try: Although I did apologize in advance; it was an “asmachta”. Why? Because any RAV who spends time in the CR, is no Rav in my book.
Also, we’re not talking “shvere sugyos” halacha here, the Mishna B’rura was quite clear concerning our discussion.
And from my read, a number of CRers seem to hold up quite well when it comes to halachic topics, including PM.
While the Internet is no substitute for intensive halacha textual learning with a Rav, PM is right in that there are a number of pretty good Internet sites with renowned Rabbonim and Poskim providing discussions and p’sak halacha on various questions and topics.
