Hi, thank you for the warm welcome and for taking the time to review my edits. I'm really sorry, I'm new to OSM editing and wasn’t aware of the copyright restrictions around using sources like the Herts CC webmap. I appreciate you pointing this out.
Please feel free to go ahead and remove the addresses and make any necessary corrections. Some of the details I added were from my own local observations, but I understand that most were based on the Herts website, which I now realise isn’t allowed.
I live in the estate as well and would love to continue contributing in the right way. Thanks again for offering to give feedback. I’d be happy to learn from you and improve my future edits.
