Janice, some members don't receive their newsletters until the end of the month. They are sent in batches (so as to avoid FaithWriters being labelled as a spammer by internet providers.) that is if you are talking about the FaithWriters regular and 500 member newsletters. You don't actually sign up for them. They are automatically sent to all members or 500 members.
If it has been longer than a month, I would say that it has something to do with emails being blocked from FaithWriters by your email provider or spam protection.
There is an archive though:

(You will need to be logged in for this one)
Hope that helps.
