Associate members can participate in all Society activities but are not eligible to hold office or to vote at the Annual General Meeting, or other meetings of the Society.
Associate membership is achieved on completing an application form and paying the subscription.
These application forms will be processed by Council, who reserve the right not to accept unsuitable persons. In the case of members elected at the last meeting of the financial year the first subscription shall cover the following year. Members of the Society who have paid at least twenty annual subscriptions, and who have retired from full-time employment, can apply to the Council for election as 'retired members'. If so elected, they will be entitled to receive all notices of the Society's activities, and to attend conferences without further payment of subscriptions. They will have no vote at business meetings, and will not be eligible to act as officers.
