unclear instructions on how to subscribe to gcc help?

[Roger Pack]

As a note, when initially attempting to "join" gcc-help mailing list,
it didn't seem like there was a way to actually subscribe, on the
mailman page:

https://gcc.gnu.org/ml/gcc-help/

This caused confusion (wait do I just send them an email?) and also
lack of communication as I only received half of the responses to my
initial query [1!]

Somebody may want to look into this...

Cheers!
