If you want to require customers to confirm their email address when they're signing up, all you have to do is include the following SmartTag™ in your checkout form:
[MM_Form_Field name='email-confirm' customAttributes='placeholder="Confirm Email Address"']
In order for this to work correctly, make sure that you place the SmartTag™ between the MM_Form type='checkout' and /MM_Form SmartTags. After this SmartTag™ has been included in the checkout form, MemberMouse will require that this field be filled out and match what's in the email address field before allowing the form to be submitted.
Here is a complete example using the default Checkout Core Page template, with the above SmartTag™ already added in:
<div class="mm-checkoutContainer">
[MM_Form type='checkout']
[MM_Form_Message type='error']
<div class="mm_left_column">
