[HOT] Validation

So it sounds like by validating we are giving some positive feedback and
makes it seem that the mapping efforts aren't for naught and ideally we
should be in a position to validate within a day or two of the mapping to
keep a bit of motivation up.

I have noticed that in the stats we say xyz has done twenty three tiles but
in reality each tile has been worked on by three or four different people
in some ways xyz has only signed off on it.

Anyway I'd better go and validate a few more on the tasks I'm working on.

Thanks John
