You followed that link OK. Now follow the other links, anytime you need details about a subject, and you don't see enough details, on a page containing a link. It's worth your time to follow the links - I promise.
Some links continue to web pages outside The Real Blogger Status, and contain additional explanations or technical details.
Please don't just read the first page, then ask questions that are answered, very clearly, on the linked page. That wastes both your time, and my time.
Follow The Links. Help Me To Help You.
