ISME no longer works with calendar year memberships.
From now on your membership is valid for exactly one year (or two in case you purchased a two year membership) . 

Accepted Payments
Visa, MasterCard, PayPal or bank transfer. Amex can be used via PayPal (you do not need an actual PayPal account for that). 

Due to the large amount of international payments, we cannot automatically renew your membership and charge your credit card or bank account. 

Cancellations of memberships are possible but non-refundable.
