Membership Expiry Policy
All memberships expire on December 31st of any given year. If you join for one year, normally your membership expires at the end of that year unless you join on or after October 1st in which case your membership will expire December 31st of the following year.
If you join as a 2-year or 3-year Member, your first year is the current year in which you join unless you join on or after October 1, in which case your first year is the following year, though you are considered to be a member from the time you join.
If you upgrade your current membership to a 2-year or 3-year membership, your expiry date will take into account that you are already a member for the current year.
