If you need to center the form, I am afraid that you'll have to use Dreamweaver to center the form. For example, put the embed form scripts into a centered <DIV> tag. For example:
Cool, it works fine, thanks!
One more question. Is it possible to check from my iPhone whether I received responses to my form.
It seems it works only with Flash and that no App exists on the store.
Thanks for your answer.
You can set up the form to get email notifications when new responses are submitted. To do that, open your form, click on "Options" tab, and then click on Email Notification section.
