Creating an Opt In Box Options

[ukbsktbll]

I am pretty new to html. I am wanting to create an opt in box to gather peoples emails/information. I would like after the person fills out their information and clicks the submit button that it will link them to another site of my choosing. Any help with this would be greatly appreciated.

Thanks for the responses. I review the link, it had some useful information. The issue is I am very new to html and don't really understand it well enough. I think I have found the way to create a form but am still unsure of how to send someone to another website once submitted.
