if you’re an ICA member, you can make a renewal payment or edit your membership account details by signing into your ICA account on the membermojo member management service. You will not need a password to sign in. If you have trouble signing in, contact us at webmaster@concertina.org. (This is different from signing into the account you use to access the member-only areas of the ICA website.)
Membership runs from 1st January-31st December each year. If you join between 1st October and 31st December, then your membership will renew after the end of the full following year.
If you prefer to renew by post, download a membership form here. For more information about ICA membership, email the ICA membership secretary at membership@concertina.org.
