A Loader is someone who has some space to share in their vehicle or on their journey to their destination and can accommodate a request to deliver the sharers goods. The loader will be notified of goods needing to be collected and will, through the website, agree to collect the goods. Afterwards this will take place in person.
A Sharer is an individual who has a parcel or goods that they need delivered somewhere. They would typically, having registered, post an article with the required delivery address. This electronic posting will be acknowledged and agreed to by a loader and that loader will then collect the parcel and ensure it reaches its destination. This will happen mostly on route of their own travels.
