Hi ndrw6!

Thanks so much for the quick response. No need to apologise! I have a lot to learn and I can totally appreciate the advantages of your methods too, especially after doing a bit of research into it. I feel I have a better understanding and feel a bit bad for querying it now. :-) Really hope my message didn't come across as rude.

You're totally right about the Cadastral Parcels and alignment accuracy, too. It's something I wasn't fully aware of when mapping this area previously. Thankfully it's not a huge offset, and I'm sure you're right to favour the Cadastral Parcels alignment. I'll look into perhaps moving the buildings to match your alignment at some point. Please don't worry about editing it yourself. I'm more than happy to do it in time. Thanks for the alignment tips!

That's a really good point about keeping the landuses separate and thanks for explaining it kindly. As I said already, I realise I have a lot to learn! You're very kind to offer to clean up, but since I'm now realising much of the overlaps are caused by the small offset, I really don't want to trouble you with it. In fact, at some point I'd like to start mapping separate 'sidewalk' footways in this area, so it really can wait until then, and I'll probably fix the alignment to match the CPs at the same time.

Thanks again for taking the time to respond and explain. There's a great community on OSM!
