Do I need an ESRI Global Account to use ArcWeb Services?
Yes, you need an ESRI Global Account to evaluate and use ArcWeb Services. If you do not have an ESRI Global Account, you can create one instantly by clicking “Create a New Account” on the top right of the ArcWeb site log in page and completing a basic form. Once ESRI has validated your e-mail, you can begin using your ESRI Global Account and ArcWeb Services.
