WordPress supports different roles. A subscriber can login to your blog and then comment without having to provide their name, email and website. On some blogs, you have to be a subscriber to comment, because the blog doesn’t allow anonymous comments, from unregistered visitors. Other roles include additional privileges. A contributor can write articles, that will have to be approved by an editor or administrator. An author can write and publish articles, without moderation from an editor or administrator. And an editor and a administratior have additional privileges. Some blogs have a team or community orientation, encouraging the registration of subscribers, authors and editors.
When a visitor registers, to become a subscriber, he receives an automatic email generated by WordPress. How do you edit the message that is sent on that email? You will need a plugin for that purpose.
New User Email Setup is a new plugin for WordPress that enables you to change the subject, text body, from address, admin subject and admin text body of that automatic email, from WordPress’s administration interface. You wil be able to personalize your Welcome email and give it a personal touch.
