Become a Member!

How do I become a SISO Member?

Attend a Workshop...
The primary way to become a member of SISO is to register for, pay for, and attend a SISO Simulation Interoperability Workshop (SIW).

This automatically confers SISO membership through the end of the following calendar year. 

New SISO Members who register for an SIW will receive their SISO Member ID soon after the close of the Workshop.

How do I attend a Workshop?

Select "SISO Workshops" from the "Workshops" menu item above.  Then select the workshop you would like to attend and follow the links to register.

Complete a Membership Form and Pay a Registration Fee...
If you are not able to attend at least one SIW in a year, you may become a new SISO member or renew your SISO membership for a fee of $95 per year.

There are two ways to submit your payment:
Online Membership Purchase/Renewal  Complete this online form, then submit a credit card payment through PayPal.  Accepted methods of payment: MasterCard, Visa, AmEx, Discover, or via your PayPal account. If you are a current member, please have your Member ID ready.

To locate your Member ID, log in to the SISO Website and select your name in the top left corner, then “Edit Profile”.  Your Member ID will be found under the “Manage Profile” tab.

 Membership Form 
Print and fill out this form, and mail it along with a check for $95(US) to:
Attn. Patrick Rowe, Executive Director
P.O. Box 781238

Please make checks payable to "SISO, Inc.".  Your SISO Member ID will be emailed to you.  Allow up to 30 days for delivery and processing.

SISO Member Database

Once you receive your member ID, you can verify and update your contact information on-line. Just log into the SISO Member Database, enter any changes or updates to keep your record current, and click SAVE. It's that easy!

To log into the SISO Member Database, you must use the email address currently listed in your membership record, along with your Member ID.  If you have forgotten your Member ID, you can click "I Forgot My ID" on the login page, and your Member ID will be mailed to the email address currently listed for you.  If you are not sure what email address is listed in your membership record, you can check by going to the SISO "Discussions" page, selecting "Options" from the top of the page, and then selecting "My Profile".  On the page that appears, you will be able to see what email address is listed by the SISO-MEMBERS Discussion.  This will correspond to the email address in your membership record.  This address can then be used to log into the Member Database, or to retrieve your Member ID.  If you have forgotten your Member ID and your listed email address is no longer accessible, contact SISO Support for help (see below).

If you believe you should be in the SISO membership database, but have NOT received your SISO membership number, please contact:
