You can choose "Manual Submit" Tab and submit your web sites manually to these Search engines.On the left Search engine panel, you can choose the search engine to submit the web site and enter your details to manually submit your web site to the selected search engine.

On the left column of the manual submission, you can see the engines on the top half, and "Login" details on the bottom half.

You can fill the login details and SEO Suite would keep this information for you to retrieve everytime you want yo submit to the manual engines.
