I’ve just finished compiling a google map showing installations of all variants of Local Exchange software that I can trace. Lots in the UK, Holland and Spain!
It is at http://goo.gl/maps/TXwPw
Anyone running an instance of Local Exchange is welcome to embed it on their website if they wish.
I also maintain a Google map of UK LETS groups (running local exchange, other software, or with no website) – see http://goo.gl/maps/cHTr3
Any LETS group is also welcome to embed this map.
All the best,
Rob
