If you try and log in and get the following message "The username xxxx has not been activated or is blocked" it is likely that your account has expired.

Accounts expire on 15 December each year and have to be renewed by the Party Administrator. You will need to contact the Party Administrator to get any accounts renewed.

If you are not sure who the Party Administrator is you will find them listed on your user profile page. Alternatively you can contact the Secretariat via email.
