When you say capture "signins", did you mean "login form" (Username and Password)? Please take note that we do not support login forms here. Creating such form will result to automatic account suspension.
However, if you mean a basic information form without username and password then that should be fine. Just create a form in the form builder and set your form URL as the thank you URL so when the form is submitted, it will redirect back to a blank form.
Here's how to get your form URL.
