please do not attach roads and buildings to landcover

You need to be careful with editing landcover using iD editor. It is not very good at dealing with multipolygon relations. This is more advanced and should be done with JOSM.

Vegane i Nygårdsparker er vel ikkje rekna som gågate? Lurte på kvifor du endra desse til highway=pedestrian

Du er klar over at det vil lage masse ekstra arbeid ved ein eventuell import av N50 i nabokommunane sant? Heile corine bitane burde vore sletta.

Kvifor var dette nødvendig? Du har laga meir rot på grensa en nødvendig og rota til relasjonar etter dette.

Please do not add municipality road refs to the normal ref= tag. Use unsigned_ref= instead.

Vi er litt "på tuppa" sidan det er mange Pokemon entusiastar som lagar parkar over alt slik at dei kan finne pokestops? eller noko slikt.

Ser ok ut for meg. Om dette er definert som ein park av kommunen og lokale folk så er det jo ein park. Men name= kan nok bytast ut med description=

Please describe what you did and not just use a generic "minor mods" for all changes.

I've reverted the edit for you ;) You'd have to simply delete the new tags. The node was probably never moved.
There is a script that is run to check for new/updated addresses from Kartverket and a separate user account (add2osm) that basically do the update. For many office buildings there are multiple companies on the same address so it is best to add a new node ;)

You're welcome. Did you see my comment on the first change you did adding a business?

Welcome. Few things. For the road there are some tagging mistakes and some useless ones. Foot and bicycle tags are not needed as "yes" would be default anyway. Motor_vehicle=no would most likely be private instead as the road is used for service personnel going to antenna. The ford tags are not accurate as the stream is probably going in pipes under the road at these points. Covered tag is also pointless to add for this.

Welcome to OSM. Please do not add more tags to the address tags. These are imported from Kartverket. If you want to add a business then make a new node with the relevant tags. Thank you.

Please do not change the ref number from NSR. It will mess with the matching of the official stop database.

Hei, velkommen til OpenStreetMap.
Ikkje så lurt å endre på adressenodar sidan desse er er automatisk henta frå kartverket. Om du vil legge til ei bedrift så lag eit nytt punkt med office=it

Vers nill å ikkje slett adresser. Desse kjem rett frå matrikkelen. Om det er feil så meld frå til Kartverket.

Please don't name houses like that. This is more like a description, not a name. It is also a very personalized thing and that should not be in OSM.

Be careful editing multi polygon relations with iD as it can easily break them. You deleted a segment near Fantoft church and caused a big residential area to disappear :)
I've already repaired it btw ;)

I've already reverted this now... Please ask before editing things that have recently been changed due to new tagging.
