The form above is simply to trick FrontPage into allowing you to write to the file content/content.php.

If saving content to that file fails, right click the form above, and make sure it's set to save it's results to the file; content/content.php   In some rare instances you may have to clear the "save to" location, then browse to the file /content/content.php or simply have your server admin mark the file as "writable"
Other than setting permissions this form does nothing.

I would recommend that you don't open a single page within this subweb, but just follow the instructions to publish it up to your server.

Instructions for publishing this subweb are located in the QuickStart Guide in your ContentSeed folder, or are available at the "AnswerDesk".

By not even opening these pages you'll prevent any potential damage, you will only need to ever publish this web once and there's nothing to edit within it.

For a full description of what files and folders need to be marked as "writable" see the AnswerDesk.
