Hosted forms are our legacy feature only available to those who have previously created one. To create a stand-alone sign-up page, check out our Landing Pages feature.
You can access your Hosted forms by going to the Landing pages & forms tab.
There is also the option to redirect them to a separate link upon completing this sign-up instead of displaying a message. All the changes you make are displayed on the preview on the right.
Once you have saved the changes to your form, they'll be reflected under the form URL.
