Hi Nick
As a first step, yes it could be linked. But eventually, would the best be to
integrate the content directly into a LearnOsm section?
As I said before, I think that we should have short sections for each task ie,
buildings, roads, etc. The content could also be easily adapted to show side by
side ID and JOSM when possible.
For example, about the buildings, you give examples how to trace buildings,
orthogonalize them. Then a step further, you show the Build plugin from JOSM.
Then a contributor would be able to compare the features of the two editors.

Would there be any problem linking it from somewhere in learnosm? I'd be happy
to have a check through for somewhere suitable and do the work.

Hi Blake
revisiting your page, it is already quite instructive bringing attention to
various aspects. It is clear and easy to understand.
Even if not yet completed, we could link to this in the Task Manager to help
beginners.

Hi Ray,
I think the only reason my mapping tips page hasn't made it anywhere
else is because I haven't finished it yet and I was sort of waiting
until it got done and was given a final once over by everyone to make
sure I am not pointing out anything incorrectly before sharing it widely
as a resource. I have most of the data for the remaining sections so the
rest should go pretty quickly.
I have been spending most of my time on validating and trying to help
with a data import which is almost done and then I can finish up the
tips page(s) and get them somewhere easier to find.
cheers
Blake
