Hello samuelzammit,

I wanted to bring a few things to your attention regarding your edits in Malta. In particular, it looks like you may have mistakenly deleted a section of trunk highway (https://www.openstreetmap.org/way/514527737) but I believe the intention was to remove an old bus stop node. I also noticed that you changed the classification of a highway segment from highway=tertiary to highway=primary (https://www.openstreetmap.org/way/29286673) resulting in a short segment of primary highway which is disconnected from the greater primary network. Primary highways typically link larger towns while tertiary highways are typically used to link smaller towns and villages (https://wiki.openstreetmap.org/wiki/Key:highway#Roads). 

I have already updated these areas, but thought it might be helpful to point this out as you seem to be a new member of the OSM community. You might also find https://learnosm.org/ useful, as it has a lot of great editing tips. The country wiki page for Malta also has some helpful policy that is specific to Malta (https://wiki.openstreetmap.org/wiki/WikiProject_Malta). 
Hopefully these resources can be of help to you, and I hope you have a wonderful day!
