Messages can be sent in the direct feedback channel via the white box. Pictures can be added by using the blue button on the bottom left side of the screen.

Messages you send can be read by everyone accessing the channel, unless you reply to a specific message. To reply to a message, please click on the arrow next to the message. This will open a conversation with the person, which only the two of you are able to see.

Every message can be highlighted by using the Markieren (highlight) button next to it.
