I need to change the e-mail address that the forms are sent to?

To do that you should follow the step here: How to properly Change and Test a New Email Recipient Address.

It will show you how to change the email, but also how to test if it is working properly.

I do however want to ask you to not post on various forum threads and open several different threads on the same subject because the system is likely to see you as spammer and remove your posts.

So in future it is best to open just a single one instead.

Thank you.
