John, we would need to routinely query Overpass to query for new contributions for a specific bbox.
We should thinkf further about such validation process. In the meantime, it is certainly possible to export the TM, calculate the bbox and then make Overpass queries.
An other interesting feature with Overpass, it is possible to query for a particular contributor. We then have a complete view of his contribution. If he make constantly the same error, easier maybe to spot and correct.

When I validate I may notice an area tagged as a building.  Occasionally I'll search the entire tile for more buildings by the same user and normally I'll find three or four areas tagged as buildings.

When I validate a project I try to validate tiles as soon or shortly after they are done and I've caught more than a few errors that way and gently nudged the mappers towards the accepted way of mapping.  However the typical tile has fourteen or fifteen different mappers contributing not just the one who marked it done.

However the really new inexperienced mappers don't mark a tile as done but these are the people I'd prefer to validate quickly to see they are mapping along the right lines.

Any suggestions please on how to pick them out and check what they've done?

Thanks John
