In the factchat, individual messages can be referenced via a connecting
line. It is irrelevant when a message was written. A simple click on
the connecting line is enough in order to return to old messages.
concrete example:
A group uses the factchat to discuss a certain topic. During the
discussion, one participant wants to refer to a message which dates way
back. Instead of copying the old message, he/she uses the reference
function of the factchat and creates a connecting line between both
contributions. By clicking on the line, the other participants can
easily return to the referenced message.
