web-to-lead form - any storage of it?  & How to create a confirmation email?

Hi all!

1. I created a web-to-lead form for a campaign, but I can´t find it anywhere after closing it. Is there any storage of these forms?

Or do I have to create it everytime new, when I want to make some changes on it in Sugar?

2. How do I create the content of the form as confirmation email to the lead?

Thanks in advance!
