How do I connect my site?
To access a site hosted with WordPress.com, login with your WordPress.com credentials.
To access a blog that is self-hosted, click on the link to ‘Add Self-Hosted Site’. For this option, enter the username, password and URL associated with that blog. If your blog is connected to Jetpack, you will also need to provide your WordPress.com login information to receive your Stats information.
At any point you can add additional blogs to your app by selecting the “My Sites” icon and clicking ‘Add a Site’. Each of these blogs can be managed independently through the app.
