When UE finishes it will not do anything to the display of the page that you have applied it to, the server behavior creates the pages and server side code to make it work, it does not do anything visually to the pages.
Any form that you have will be just as it looks to you in design view in DW. If you only want to send to people in your recordset you can set the to address to be the value from the recordset and loop once per entry in the recordset.
You could have a form with whatever info you would like to show and have a submit button. If the action of the form goes to the same page you can use this submit button as the trigger for the UE server behavior.
