[Talk-GB] School mapping - Who's involved

[Dave F]

Re 1c)
Unsure what two queries you want to compare, but OT does allow 
difference comparisons by first saving each query result to a variable:

http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Sets

http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Difference

Example:
http://overpass-turbo.eu/s/e7s

This returns all edits from the last day that weren't by me. Obviously 
you'd need to change it to your user name to see any results & you can 
vary the day/hour.
