As far as I know, Λεωφόρος Ελευθερίου Βενιζέλου is not a national road, according to any source that I have seen.

I disagree with making that national road secondary: Just because Karystos is merely a town doesn't mean that the Greek government considers the road to there unimportant.

Hi, you unintentionally merged a node of a major road to the wrong road. This is why I do not prefer using iD but Potlatch instead.

Hi, I should clarify that if the actual ref is different, then that is fine: however, if the "nat_ref" is the only value, then "ref" should also be that since "nat_ref" is not supposed to completely replace "ref". :-)

Sorry but I need to elaborate further on this: you appear to be removing information from some relations such as relation/3867724, relation/56741/history and relation/279482. Please see osm.wiki/w/index.php?title=London_public_transport_tagging_scheme on how we tag bus routes in London.

Why are you removing information from some relations?

Hi, "nat_ref" is not supposed to completely replace "ref", if that is the default (national) ref on the maps.

Hi,

It's a UK motorway signal that tells drivers about the adverse condition of the road ahead. It does not give directions to any town, but it only tells drivers about the adverse condition of the road ahead when it is needed. Usually, they are blank when there are no adverse conditions.

Okay: changeset/34774928

If you can find a better way later please let me know.

It's a motorway signal that you find at the centre of the carriageway (http://www.cbrd.co.uk/articles/mixed-signals/matrix.shtml). If highway=motorway_signal is not the right way, then what tag would be better?

Hi,

I have been led to think that this changeset was "spamdalism" (spam and vandalism), because the edit overwrote an important road in London, and the business that replaced it was overly promotional.

Businesses do no go directly on the roads. Also, businesses have to actually exist in a building and not be overly promotional.

That changeset, especially without a changeset comment, was clearly vandalism. Please don’t do it again.

Google Maps as a source? Not sure if that's allowed.

Oh, I forgot to say that impromptu diversions, like skipping the bus station, may occur (albeit rare) if it is necessary to provide an even frequency, or the bus station is heavily congested.

I am sure that the regular bus stop for 73 is the same bus stop as route 30, the last time I was there. Note that for anyone not aware yet, the public transport scheme has changed recently, we now map stop flags and stop positions separately. Also, some buses stop a bit back if there's a queue, if anyone else doesn't know about that practice.

How on earth EO56a/EO91 is a motorway? I know that only standard blue direction signs exist there.

I strongly disagree with the changes flierfy made: mph is the rule of the rails in nearly all of the UK rail network. I also cannot recall any FoI or similar request regarding metric speed limits on the ECML or the CTRL.

Hi, kindly note that London bus routes are now using the new public transport scheme, and not the traditional single relation we were used to.

See osm.wiki/Bus_routes_in_London for more info.

Hi, why did you delete names from some ways, like way/352319225?

Pressing "R" accidentally may be a problem because that key copies all the attributes from the previously selected way. This is why I personally prefer using JOSM instead of Potlatch, 95% of the time.
