Creating the Form

Finally, you can work on the form. You need to allow for two form fields -- a
name

and an
email
. You
also know that you need to post to welcome/subscribe. That ' s all you really need in order to create the
form. In the example below, fieldsets and labels are used, but other approaches are equally valid.

One important note: The Subscription form has been added to the home view. As you can see, it is a
simple form that prompts the user to fill in his name and e - mail address. In this particular case, the
example uses a fieldset to delineate the form, but you could use any visual design convention to separate
it from other parts of the page.
