Changing from a monthly to yearly plan:
You can easily change your monthly membership to a yearly membership by logging in and visiting the Account tab. Either click on this and select “Change Membership Plan” in the drop down menu or click on My Account > Subscriptions > Change Plan.
Changing from a yearly to monthly plan:
You can use the same procedure above to change from a yearly membership to a monthly membership. But please be aware that making this change any earlier than the 12th month, will forfeit any remaining months on your yearly subscription. This is because Stripe or PayPal will cancel your yearly membership and start to charge you a monthly fee immediately.
