If you are a regular member of a league without any specific administrative rights, the best way to create an account on Trackkarma is to receive an invitation email from your league administrator.

In the received email, you will find a link allowing you to create your account. Click this link to access the registration page.

If you created your account yourself before receiving an invitation, you might be stuck on the following screen. Don't worry; simply ask your league administrator to send the invitation to the email address you used to create your account. Once you receive the invitation, follow the instructions to complete the creation of your account.

Make sure to provide the same email address to your league administrator as the one used to create your account. Otherwise, the invitation will not work, and you will see the following error message:

Then ask your league administrator to send a new invitation to the correct email address. Alternatively, you can log out of your current account and click the invitation link from the email again to accept it and create a new account with the email address used in the invitation.
