Should I work with someone through the messaging area?
No you should not work with someone through the messaging area. If you do, you aren't protected by Vocalizr Payment Protection, or by our agreements.
However, if you have already given a demo through the messages, we suggest you ask the user to Create a Gig using Hire Now to start work with you properly. Do not start making changes and iterations and uploading them through messages.
This way you are protected by Vocalizr Payment Protection, and you will have proper agreements in place.
