If you want to offer visitors to your web site a way to sigup to your contact list, you can create a subscription form in the system to add to your site. You will need to have a little experience with HTML to add the form to your web site. 

To get started, click the "Website Forms" link shown in the top right-hand corner of the system. This will take you to the "Manage Website Forms" page. Website forms are special forms that you can create. You can create website forms to accept contacts, for someone to unsubscribe, modify their subscription details or send an email campaign to their friends. 

Click the "Create Form" button to create a form. Type in a form name and make sure you choose the "Subscription" option from the "Form Type" dropdown. If you aren't sure what any of the fields are, just move your mouse over the help icon next to that field: 

Click the "Next >>" button. Depending on which form options you chose, you may or may not be required to enter more details. Again, if you are unsure of anything just move your mouse over the help icon next to the field and read the help text. 

Once you've created your form you'll be taken back to the "Manage Website Forms" page. Simply click the "Get HTML" link next to your new form and paste that code into your website to add the subscription form to your site.
