In the
'Reggaechat" there are only user of
this website ( perhaps some informers ).
All the other rooms are content of other websites as well.
You should not post any kind of
promotion there !
To inform someone personally you should 'whisper' (flüstern) to her/him or
invide him/her to a new own room ( and probably lock the door ).
Best you check the
help (Hilfe) !
