When you sign up for an Organization account you have the ability to add a logo. When you do this the logo will be shown in the upper left corner of the website for you and any of the coaches you add to your organization. It can be a nice little feature that adds some of your own branding to the website for you and your coaches. Be sure to watch the video for a full demonstration. Here are the steps to add your logo...
Click "My Account" in the upper right corner and then select "Org Profile"
Upload a logo that represents your Organization in the field title "Organization Image".
You can replace the image at any time. Just keep in mind the image you upload will appear in all of your coaches accounts.
