The address shown is not the school but the alumni contact.
Add Your Alumni Group: When adding a listing, categorize by the state of the school, not that of the contact. If your site is for a single class, prefix the name of the school to the title, so that it will sort with the school in lists. Listings are activated after review by AMS. There is no charge to list an alumni association. Vendors pay a small annual fee.

BTW, if you're here to spam the form, don't bother. Listings are only activated after review by the editor. Please don't waste our time or your own.
