Sign in to Adobe FormsCentral, open the form, and select "Share" button on your lower left corner. Select "Publish Responses" and you will see the dialog. After you published it, on bottom pane click on "Published" to expand the menu and you can now "Copy the link" or "Copy the embed code".
You can place the link or the embed code in the source of your web page. Or you can send the link via email.
Hope this answers your question,
