[Talk-GB] Fixing non-closed polygons in the United Kingdom

[Dave F]

My ears are burning...

This highlights my long held belief about 'validators' such as 
maproulette which induce contributors to believe that the OSM database 
is 100% definitely incorrect without doing any personal research. The 
delay in database updates, in this instance.

Please pay attention when editing in OSM. Don't amend unless you're 
absolutely sure.
