Subject: Re: OT: Mail list for learning C++

In the old days, I used to look at
https://groups.google.com/forum/#!forum/comp.lang.c++ (except the google
part, but that's where the group now has its home). More modern might
be #include
<c++> Discord <https://www.includecpp.org/> and r/cpp_questions

Have a look there?
