Michael Linton is probably best known for having designed the LETSystem, which is an open form of money, or personal and practical arrangement of community currency. The first of very many instances of this design was originated in Comox Valley, BC, Canada in 1983.

Many if not most of the hundreds of LETS within the UK, Canada and Australia and probably thousands of similar systems elsewhere, involve a members' agreement identical to or based closely on Michael Linton's original LETSystem design.
