Membership is extended till the end of the calendar year +1 for new members who apply for membership in August or later.

The membership renewal button in your membership account (login required to access your membership account) would only appear in the following cases:
- your membership lapsed and is not considered active anymore
- your membership is still active but is about to expire within less then 3 months
