If you got an invitation mail from your employer/admin, you can directly join your organization as a member. Otherwise, you will need to use this method (alternative to invitation mail):

  1. After signing up and verifying your email address, you will be presented with this screen.

Click on "Join An Existing Organization".

2. After that, you will have to Enter the Organization code. Please ask your admin to follow this guideline on finding the organization code.

3. After you have entered the code, a joining request will go to your organization owner. He will accept you into the organization.
