Ok I've fixed it now.

Did you mean to end up removing the name "Runnymede Close" in this edit? It's broken a match against Ordnance Survey Locator: http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=868564

Good work.

Consider asking the author of the previous changeset for his source?

Eek, more road-merging resulting in auto-merged-semicolon-separated road names (and refs) breaking OS Locator matches here http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=890450

Did you mean to switch the name= on Passmore Edwards Court to an addr:housename=? This has broken a match: http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=907839

According to the previous edit on Barrow Road, "Road was renamed from Barrow Road to Abbey Road" (osm.org/changeset/21183173) and this edit now disagrees with Ordnance Survey Locator (http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=19772). Are you sure this is right?

Did you mean to delete Cottam Hall Lane in this edit? http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=204564

Are you sure about this edit? It disagrees with Ordnance Survey Locator which thinks it's called Tun Lane only south of the bend: http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=810890
"Westoff Lane" has now disappeared.

Are the following roads being demolished/changing name or is this a mistake?

Did you mean to delete Middleton Mews in this changeset? It's now leaving a hole in my QA tool:

Fun tip - if you select the building and his "s", the editor will square up the edges for you.

These are all really useful edits - remember to make sure footways etc. are actually connected to other ones where it is possible to traverse between them so that e.g. the router can pick them up. Should the steps to the "Acredale" parking lot from Church Place be connected at the parking lot perhaps?

Very good :).

(Caught us out there...)

The Grove -> Fieldhurst Close: are you sure about this? 3 things...
1. OS Locator disagrees with you http://ris.dev.openstreetmap.org/oslmusicalchairs/map?osl_id=742886
2. Fieldhurst Close is the road one down from this one.
3. The road you've assigned the name to is not a close.

(some people get confused by the fact that when you re-click the tag name of an already-tagged object it untags it [so you can select a new tag], which is a bit of a user interface... oddity in my opinion)

Great stuff. Cut-throughs are incredibly useful things to add to OSM. Keep up the good work.

Hmm. You've managed to turn Sole Farm Avenue into a footpath here and the line you've created between it and Childs Hall Road hasn't been tagged as anything, so OSM doesn't know what it is - it could be a fence, a river, anything. To assign tags to objects you select them and then use the menu on the left hand side to choose what "type" of object it is. You can then add further properties to the object from there.

Good stuff. I just made a small fix - we tend to put most of a feature's tags on the enclosing area, rather than the building.

Keep it up.
