PHP script discussion mailing list

Pardon me if I am in the wrong place. Move me according.
I am frustrated - not a PHP programmer. I am looking for a
free PHP script discussion mailing list
I see alot of
free PHP script annoucement mailing list
paid PHP script discussion mailing list
free PHP script discussion forum
I searched in HotScripts.com, supershareware.com, sourcecodeonline.com,
as well as DuckDuckGo search engine. I find it hard to believe that
there is not one
free PHP script discussion mailing list
Whether it uses mySQL or not is not important. Are you aware of such a
list?
Thank in advanced for your help.
