Just choose one or mode social accounts/profiles in the account selector:
Click in the "Select social media profiles" to pull down to and select. Or, start typing and they'll auto-complete.
Of course, you will need to have added your social profiles added in RiteKit. Note that you can add social profile any time, and with any RiteForge account, there is no limit on the number of social profiles you can add.
Note that no third-party apps are able to publish to Facebook Profiles or Groups anymore; Facebook took this back.
