By attending an AOGS Annual Meeting, one can become an AOGS member. Membership in AOGS is only good for three annual meeting years following the most recent one that you attended. One must attend an annual meeting at least once in each of the three years to keep their membership active; else, it expires. This is as illustrated below.
