Logos for Sports Organizations
Organizations that have their teams on Premium and Ultra plans can add a logo under their organization's Settings > League Settings tab. If you have it set for Organization-Wide Settings, this will filter the logo down to your teams as well (there can be a small lag before each team is updated).
If you don't want the logo to appear on all the teams, change your settings to Team Controlled Settings, then add the logo using the steps above.
If you do it this way, then the logo is set up for your organization, and that logo will appear on registration forms and be included in organization and division emails sent from the Messages tab by a commissioner. The team logos will need to be configured for teams at the team-level. You can read more about team logos here: Configure Team Logo.
