Greetings! Welcome to KSTA!
Your username is chosen for you. It's the email address that you supplied when you filled out the membership form. For your first login, the password is "password" (without the quotes). After you're logged in, you can go to Member Update under the Members Only menu and change it to suit your preference. If you run into any problems, you can email to firstname.lastname@example.org for assistance. It's possible that a typo in the email address could create a mismatch or there could be some other minor issue. You can always call the KSTA office number for help as well.
Note about NSTA/KSTA joint memberships - The NSTA folks do not notify us immediately when a membership is purchase through their website. That can lead to a delay before a new purchase gets entered and activated on the KSTA site. Again, feel free to contact us if your KSTA membership should be active but is not.
