  2. Complete the appropriate AAS Membership Form.
  3. Obtain nominating signatures from two AAS Full Members. These signatures are essential to becoming an AAS member. The nominating signatures can be made directly on the Membership Form or endorsements can be sent via email.
    1. If you prefer the electronic method, write the name and email address of the endorsers in Section #4 of your Membership Form.(Section #6 if you're applying for International Affiliate status.)
