1. To sign up for a membership, you will need to register using one of the 6 networks. You will use your log-in credentials for this network to access your membership. Be sure to remember which network you choose, as you will not be able to change this once your membership is created.

2. If you do not already have an account with your network of choice, you may sign up by clicking on one of the following links:

AOL   Google   Yahoo!   OpenID   Facebook   Twitter

Please note: If you have not  yet signed up with one of the above networks, do not enter your name into the field below. We have no prior record of which network you used, as  you have not yet completed this step. If you enter your email in that field and click continue, you will encounter the below error. Please click on one of the above networks to log into your account.

3. Once you have successfully logged in using your credentials for the network of your choice, your email address will be the default address where your receipt will be sent. Check the box to agree to Topspin's Terms and Conditions to continue.

4. Select your payment method, and then enter your billing address.

5. Enter your credit card information. If you need to edit your billing address, you may click the (edit) link to go back to the previous screen. Please be sure the information you enter is correct, as any inconsistencies will be flagged as fraud, which will prevent your order from being successfully processed. The total amount shown will be charged to your credit card once you click Continue to submit your purchase.

6. Once your order has successfully been processed, you will see a confirmation screen, which will give you the option to join the mailing list. If you do not wish to be added to the mailing list, you may uncheck this box, and close out the window using the X in the top-right of the screen. You may click the link to view your receipt, which will also be sent to the email address you have provided earlier in the purchase flow.
