When you have an open request with another user, you can remind the other partner to react to your latest enquiry. You can use the chat field to send you partner a message to remind them to respond.
In case a request is accepted, you can as the user of containers remind the supplier to provide a release reference if it has not been provided. You can also remind the supply to provide drop-off details once containers have been picked up.
As a supplier, you can remind the user to pick up released containers by clicking the button above the chat. You can also ask the container user for a time-line of when the containers will be returned in the chat.
