S2 Members Customer Renewal

Good morning all,

I have a site that has two different membership levels. One of them is $125 and the other is $75. Do I need to create two different renewal forms so that they can renew on each different level?

Also all of the memberships are based on a calendar year not on a monthly so every single one of them will expire on December 31 no matter when they signed up. How can I force a downgrade after the first of the year.

Lastly I have enabled the EOT Renewal Reminder email. Does that automatically know what level to charge them when the email gets sent out?

Thanks in advance.
