Announcement list code


When I first joined, I located code to set up a page for people to sign up for my announcement list. I can’t find it now and my page got messed up.

Can anyone direct me to the right spot to find the code for setting up a page where one can subscribe and unsubscribe to a person’s announcement list?



This should be the page >,PHP&Databases/_Announcement_Mailing_List#The_basics
