Setup of M2P confirmation of email address

Hello,
I recently purchsed the plugins and I have a few questions regarding the Membership 2 plugin id appreciate a bit of help with.

1. Is there member confirmations? I have the Mailchimp addon installed and have tested this BUT if someone registers with a fake email address to my free account they still get access to the protected content without confirming it is a real address. Is there any way to restrict acccess until they have confirmed their email address, ideally through Mailchimp.

2. Am I able to ammend the ms-alert-box and ms-alert-success ?

3. In the login screen, the link at the bottom has "register/?step=register". Is there any way to change this to simply "register".

Warm Regards
