I know this may be a little confusing and you may have missed it, but there's a "Blogs" option on the white menu underneath the main Psych Central site menu bar. In the drop-down for that menu, there's an option entitled, "Get yours" (meaning get your own blog). It takes you to our user-created blogs site that has more information:

You simply need to send me a PM requesting a blog and I'll tell you privately how to do so. (We do this in PM to prevent spammers from requesting blogs.) Thanks!
Best,
