To view your messages select Messages from the top menu on your Dashboard.
If you know their name and that they can be contacted on Frankfurt Rights (Some users opt out of personal messages) you can click on "compose" and start writing their name in the "To:" field. If the system recognizes the name, it will start suggesting users and you can select the appropriate recipient from there.
You can also send a message to another company - rather than a specific person - by navigating to the Rights Portal of the company you would like to contact. Then click Contact and enter a subject and you message into the text boxes. Click Send to submit your message.
For further information please see: How do I search for members?
