To get started, please click the title of the membership type appropriate for you. Membership types are fully covered in the NASG's Bylaws, ARTICLE XI, but the main points are listed below.
You can, optionally, flag the new membership as a "gift" for another person. To do so, check the "gift" box on the application form, and fill out the information on behalf of the other person. You'll be making the payment, and only you will receive the payment confirmation, if paying via PayPal.
If you are applying for NASG membership and you also want to purchase one or more of the NASG's Store items that require NASG membership, add your new-membership application to the shopping cart first, and then continue to shop for the item(s) that you want. The NASG web site's shopping cart is set up to recognize a new-membership application, and considers that to be valid enough for you to also purchase NASG-only items at the same time.
