Go to console.nametag.co/signup, then follow the two steps to enter your work email address and your company name. This creates your organization in Nametag. Optionally, you can upload a logo, but you can also do this later.
If you want to join an organization that already exists, for example if your coworker already created one for your company, you'll need to be added as a user. This page explains how to add members to your organization. Find the invitation in your email and accept it. Remember to use this same email address to sign in in the future.
After you've signed up, you can login any time at console.nametag.co. Make sure to use the same email address you used to set up your account in the first place.
