Thanks a lot Chris,

I like the way you've split the tasks, looks pretty sensible to me. I agree
that people can just comment they are going to survey an area or 2 or part
as appropriate, then come back and work on it later.

Main issue is this just covers area 3 (although there is a chunk south of
Cluny gardens missing). There's also another area of similar side covering
north Edinburgh. Is it possible to add these too?

Cheers, Donald
