Hi! Welcome to OSM! Thanks for your contributions here. :) Just one minor point, I notice that several of you were editing at the same time, and 3 of you have been editing at the same place, and yous each have put the same building at the same time. Maybe in future don't edit the same area at exactly the same time as other mappers? If you're using a tasking manager then that should take care of that.

Here's the 3 changesets:
changeset/33494939
changeset/33494627
changeset/33494507

No problem! 🙂 We all have to chip in, and we can make things better

In this edit you added some untagged nodes. I've removed there here ( changeset/45831785 ).

I've removed those "brownfield" sites, since they don't seem to be brownfields at all. If you have any questions, let me know. 🙂

Hi! I fixed up (here changeset/45830957 ) some of the rivers you mapped. You had 2 rivers crossing, but it's better if you join the OSM 'way' together

Hi! are you sure about all those [brownfield](landuse=brownfield?uselang=en-IE) sites? They don't look like much. Those names look a little off as well..

Hi! I think 3 of you were mapping this area at the same time ( changeset/42655091 changeset/42654784 changeset/42655056 ) and yous added lots of overlapping buildings (which I removed here changeset/45589291 ). If there's some sort of map-a-thon, try not to work at the same area, and update your data before uploading

Hi! I notice in this edit that you added lots of coastal details (👍), however some of the mapping is a little confusing to me. You have some areas which overlap completely and are tagged differently. e.g. way/303267379 and way/303395670 one is tagged as a beach the other as a tidal flat. But that little area is either one or the other! It's either a beach or a tida flat, surely? I'm gonna clean it up a little bit and remove the beaches, becuase they aren't really beaches, they're more tidal flats.

I'm not local, so I'm not sure if they have a name. I'm half tempted to delete them, since I think those little piers wouldn't be named.

Why remove the walls? There are plenty of walls and hedges and stuff mapped in OSM, why not keep them? You can see them from the aerial imagery (though they look a little like hedges to me).

Hi! Welcome to OSM! I've been looking at this area. I've fixed up the tagging of St. Mary's, I wonder if you wanna give it a once over and add some more information?

Hi! You've added name=Athlone to all the little piers at Athlone (e.g. this way way/202136127 ). Is that accurate? Is the name of that pier "Athlone"?

I saw that you had lots tagged of ways as walls. And they are still there. It's just that you had ways which were overlapping on top of them.

I've deleted them last night, sorry! I hope it's OK. There are still loads of walls there.

Hi! It's great to add lots of landuse stuff. It really makes the map more filled out. However you've added a lot of untagged ways on top of the landuse areas you've added.

Hi! In this changeset you added lots of buildings in Marian Avenue/Place ( changeset/10874908#map=18/53.02922/-7.30670), and many of the buildings overlapped. I've cleaned it up now. Do you know about the JOSM terracer and building utils plugsin? :)

Hi! Wellcome to OpenStreetMap! I see you've added a lot of viewpoints. Are you sure those are view points? I've briefly been there and I can't remember anything that looked like a true viewpoint like that.

Hi! Welcome to OSM! Thanks for adding lots of details in this area. Just one thing, be careful with the "name" tag. You shouldn't say "name=Grass" for just a grassy area. The landuse=grass is enough to record that the area is grass. You should only use the "name" for actual names. Likewise you shouldn't add "name=Residential Dwelling". The "name" value for houses should be the real official name, kinda like "name=The White House" :)

If you don't know the name, it's totally OK to just leave it blank!
