How can I add a different social media link to my project?

You adapt the social media or other icons for your project in Skins.

Click at the project where you want to change the url or other settings. You find the icons at the end of the Style tab. Click at Social or Other to adjust your icons. 

At Link Url under the icon's name, you can change the url or make other changes to this icon.

You are only changing the icons and their settings in this project.
