I have two questions:
1.) Do you plan to upgrade your plugin and add SEPA Direct Debit (IBAN/BIC)? I think normal ELV is dead after some weeks/months. Here is a potential image you can use for the SEPA integration: http://blog.visma.com/wp-content/uploads/2011/11/SepaLogoEN.jpg
2.) Is your plugin fully compatible with WooCommerce Subscriptions (http://www.woothemes.com/products/woocommerce-subscriptions/) ?
Thanks in advance!
