I looked at the web site of gawk. But I don't find a more appropriate
mailing list to ask user questions on gawk.

It says on the webpage, "awk has one mailing list: <address@hidden>.
It is used to discuss all aspects of Gawk. This is an alias for the
bug-gnu-utils list, if you want to subscribe or look at the archive."

Therefore, I thought that I can send questions to this address. Where
should I send future gawk user questions?
