We currently have a wordpress blog for a small business. The blog is open to the public and should remain that way. We'd like certain members who have paid for the service to have access to a page where they can download a PDF of a monthly newsletter. Will aMember work for this function if we purchase the wordpress plugin with it? I suppose we would have to enter the permitted users manually as we get payments via phone and mail as well as online. Is this correct? If not, any other suggestions?
