LETS are are local community-based mutual aid networks in which people exchange all kinds of goods and services with one another, without the need for money. LETS were invented in Canada and are now the most widely used model for community currency systems in the world. There are LETS in the UK, USA, Canada, Australia, New Zealand and Ireland. LETS use 'community credits' as people do not have to make direct exchanges. People earn LETS credits by providing a service and can spend their credits on whatever is offered by other people in the scheme. This could be childcare, transport, food or home repairs, or sharing or rent of products. There is an organisation in the UK that supports the LETS in the country: www.letslinkuk.net/
This is a really interesting scheme. We should SPREAD it to other countries!
