Figuring this thing out.

So, it appears to me as if one can not create a blog here on TN and then continue in the same blog with future updates or subjects ... that one must create a whole new blog in and of itself. That sucks. How can people follow someone they enjoy reading about if their blogs are spread out and not associated one with another? Or is that how all blogs work? I am new to writing a blog, so I don't know the answer to either question. Oh well. Maybe someone could PM me about how this all works. Don
