Follow up on Techeiles Question

Follow up on Techeiles Question Question: The article said that the person was told he "should" continue to wear techeiles.

Hot Mikvah on Shabbos

Question: I try to go to the mikvah every day before davening, would i be allowed to go into a hot mikvah on shabbos?

Is it a mitzva, perhaps, to stake our claim as the righ ...

Techeiles

Techeiles Question: I have seen the Rav's teshuvos about Murex techeiles, and the Rav has not been supportive. In the Mishpacha Magazine over Pesach, the Rav was quoted as permitting someone (if I recall correctly it was one of the Rav's drivers) who was wearing techeiles to continue to wear it.
