Confirmation Email & New Affiliate Approval

I have 2 questions.

1. Using the light version, is there a way to edit the title of the email that goes out to new affiliates? Currently, the email title says “WordPress” and I would prefer it to say my business name.

2. When someone applies to become an affiliate they are automatically approved. Is there a way to make them wait till I approve them?

Thanks in advance for your help.
