Can you describe in what ways these amenities were wrong, such that they needed fixing?

I can't help thinking Pompey would be better for the "loc_name" tag rather than short_name

Do you have any source for the name "A32 Road (England)"?

Surely its simply 'A32' - it's quite self evident that it is in England.

Also something describing your changes would be good. See:
osm.wiki/Good_changeset_comments

You may want to investigate the key opening_hours
opening_hours=*
e.g. opening_hours=24/7

Welcome to OSM :)
You may want to ensure your edits are localized geographically / be relevant to the changeset comment.
Otherwise how does editing in Malawi relate to changing Shoreside County Primary School in England?

Changes now reverted after no response.
See changeset #35658141

Sorry, my mistake - this is all right now.

I may have confused myself but may be one of the previous changes wasn't necessary (which you then may have subsequently fixed).

Thanks for fixing it up and adding in the Farm / Farm driveway (which is what I should have done) to make it more obvious why the main road is two way.

One can see why it would show up on a GPS analysis of oneway traffic as only very, very few people would be using it in the opposite direction to the main traffic flow.

Again you might want to review these changes in detail;
as I looked at this location a couple of weeks ago that TrafficFlowDirection had highlighted - but is a false positive.
At least one part of Mill Road is not one way, as you can left from the residential offshoot bit of Gosport Road.
Again this can be seen/inferred from Bing Aerial imagery.

Segensworth Road is not one way at the SW end, as it has access to the buildings to the East.

i.e. be careful in following what TrafficFlowDirection says (if you were using that tool), as I looked at this location a couple of weeks ago that it had highlighted.

One can clearly see the arrows on the road from Bing Aerial imagery.

I don't understand your series of edits in what they were trying to achieve and seems to have straightened/moved Grantham Road and removed Thirlmere.

Be sure to ask if you need help or perhaps it would be easier if I reverted those changes so that you can start again

Swanwick Railway Station already exists.

Isn't is best to add the address information to the existing node?

Botley Railway Station already exists in this node:
node/9509195

Perhaps is best to add the extra info into that node.

I see, this might have been what I've been hearing on Facebook too.

Wouldn't it be better/simpler to delete the Node: 1495236772 (rather than the primary tag)?

You seem to have removed the
amenity=bicycle_parking tag in this edit.

This don't seem quite right.

A "cash point" is better defined using the 'amenity=atm' key/value description.

See amenity=atm

How does a single node (3713970949) intersect with itself?
At least you've recreated it. But deleting it and recreating seems unnecessary...

"#hotosm-task-60" Doesn't really describe why you made the changes you have.
I would not have thought Portsmouth would be part of a HOT task.
The construction areas seem entirely made up - does not match aerial imagery nor anything I'm aware of (living locally).

Your changes seem to include untagged lines, which don't add aid the map much - since one can't guess what a line represents (a footpath?, a road?, a stream?, etc...) without a tag to describe the feature.

See osm.wiki/Tags

Further some of the ways seem to be over the top of existing ways.

There are probably missing permissive tracks/paths in this wood - which I guess you were trying to add?

I've now reverted this change.
