Your wiki server can allow anyone who has an account on the wiki server to create a personal blog. It can also restrict who can create blogs to a specific group of people.
To create a personal blog:
While viewing My Page, click Blogs.
Click "Create my Blog."
If a My Blog link appears on the right side of the page, you've already created a blog.
If neither the button nor the My Blog link is shown, you can't create a blog on the server.
