Hi George - is this a question - if so you can setup the basics in 30s yes - populating it with meaningful content will take a little longer.

All the best, Mark

Normally all themes has link button. Is this the link button you are looking for http://d.pr/i/mOr5

Is the button completely missing, or is it disabled (grayed out)? Is it the same result whether it's a page or post? I would assume it to be the same since it's the same editor effectively
