How does one start a blog on this site?

Msdaisy, I see you have been posting questions/discussion in the past, so I assume you are talking about the professional bloggers who occasionally will post a *blog*. Your best bet is to use the following link and ask the owners of the website what are the qualification to become one of those professional bloggers: https://www.agingcare.com/contactus.aspx

You either post a new question, or you make a new post in the discussion area.
