[HOT] Validation

I tend to vary it a bit - My normal comment in the box is something like
'imagery was probably slow to load which is why they were missed', but then
I often add a link to something like
and a casual comment about round huts being explained there, just in case
the mapper isn't recognising them.

Sometimes I'm quite happy to do a lot of missed mapping on the basis that
it can be quite relaxing & pleasant to do so!  If I do add the missing
bits, I normally still add the link & send the message just in case there
is a learning point. When I'm validating for a mapathon I try to actually
see the mapper & get them to add the missing bits.

Although quality control is important, helping each other is more
important. I don't like to see squares invalidated for little reason as it
tends to lead to ill feeling.

I only ever invalidate if there is a lot missing though - we can all miss a
couple of buildings on occasion. I have genuinely had imagery fail to load
properly, so I missed an entire area at one point, and only picked up on it
when working on the adjoining square & realising there had to be something
I had missed.

Keep up the good work.
