I think you'll find there's no such thing as an "allowed" or "not allowed" value for a tag - we're not proscriptive about such things.

You appear to have managed to create a duplicate of Sheffield Street somehow. I've removed the extra one now.

It also seems to like adding silly "test" roads in the middle of Nigeria:

osm.org/?lat=9.99961&lon=10.00212&zoom=17&layers=B000FTFTT
osm.org/browse/changeset/914200
osm.org/browse/changeset/914200

Lesson 3. Pay attention to the words "You need JOSM version 1529 or later" in the JOSM banner message about the 0.6 API update ;-)

I'll also add that what you must not do is to just upload your original data again with the extra tag added - if you do that you will leave two of everything in the database.

It's probably based on the planet dump, which means it will only update once a week at most.

No, the solution is not to split the way. Nor is it to provide a means of manual location. The solution is to fix whatever renderer is not choosing the right location.

Just to make things clear - that isn't my site, it's Matthew Somerville's, so if you have suggestions for improving it you should aim them at him.

It's a bug that was fixed within half an hour of somebody mailing me about it (which was about two hours before your post).

...except that surgeon also appears to be the only editor of that way as well!

I think surgeon may have been referring to osm.org/browse/way/24866162 which is under the way specified. Presumably in attempting to remove it the other way was accidentally added.

It's because mapnik does not support vector icons at the moment - please feel free to fix this limitation.

Deleting an account does purge (or at least hide) that user's diary. The account wasn't deleted when you looked though. It is now.

The database that drives postcode searches is primarily derived from the data entered at www.freethepostcode.org and www.npemaps.org.uk and not from anything in the main OSM database.

I'm not sure how often it is updated - we query it via a web API on the npemaps site I believe.

I believe it is supposed to pick up your browsers preferred language - either that or the operating system language setting. What it actually uses is a flash preference value, but that in turn comes from the browser and/or operating system.

I believe the next version of gpsbabel (or indeed the current CVS code) has support for this logger already via the mtk input driver (use "-i mtk,m241" as the input format).

Users are keyed off both the email address and the display name - both are unique and either can be used to login.

If you want to change your email address then send me a message - it isn't possible to do it yourself yet but I can do it.

The problem is that you're trying to use a prehistoric version of JOSM that is still trying to use API 0.4 which was dropped the best part of a year ago. Get a current version that uses API 0.5 and you'll be fine.

Even better would be to tell us what happens when you try and upload it - the error message will probably be far more useful than the file itself at least in the first instance.

That said it looks like it is a list of waypoints and we don't currently import those so uploading it probably wouldn't be useful anyway.

Works fine for me (though there is no history for that way - there is only one version in the database).

Perhaps your browser does not display text/xml documents correctly?
