So, some years ago, I stopped using my Yahoo! acct, because the service was so intensely miserable, I ONLY resumed using it because I was required to by the CFM, and Google gives me the creeps, as it should any historically informed, thinking person. Well, now Yahoo! Mail has been down for days, so I sure hope you folks at the CFM aren’t sending out anything important that way…
I have several Yahoo accounts and have not noticed any major problem with it recently. 11 Feb 2018.
