Here is some Code4Lib mailing list administratativia.

The mailing list is twenty-one years old, and I supose it is now old enough to vote.  :-D  There are about 3,800 subscribers from all over the world. The largest email address domain is gmail.com, and I suspect most subscribers are from the United States. Archives of the list's postings exist at:

 * https://lists.clir.org/cgi-bin/wa?A0=CODE4LIB
 * http://serials.infomotions.com/code4lib/
 
From the charter:

 The purpose of code4lib is to provide a forum for discussion
 of computer programming in the area of libraries and
 information science. Subscribers are welcome to discuss the
 application of particular programming languages and to
 discuss the general issues, techniques, philosophies, and
 even history of programming for and in libraries. There are
 other venues such as web4lib, xml4lib, perl4lib, but this
 list hopes to encourage the holistic use of programming
 languages, and to provide useful discussion on how to select
 the right tool for your particular job. Hopefully everyone
 will learn a thing or two along the way...
 
But now-a-days, the list is much more general and about the overall use of computers in libraries.

The mailing list is an implementation of the venerable LISTSERV software, and it is generously hosted by the Digital Library Federation (DLF) / Council on Library & Information Resources (CLIR). [INSERT CHEERS OF APPRICATION AND ROUNDS OF APPLAUSE HERE.]

Two more things that seem to have gotten lost to the ether. First, people posting to the list are expected adhere to the Code4Lib Code Of Conduct. See:

  https://github.com/code4lib/code-of-conduct/blob/main/code_of_conduct.md

Second, and similarly, the mailing list is not a bulletin board of lore. Instead, it is a community of real people who are expected to take responsibility for what they say. In that vein, when you post messages, please sign your name and affiliation so bits of provenance can be garnered about you; the LISTSERV software probably obfuscates your email address and anonymity is discouraged.
