Hi German,
1. Use the Bing imagery where possible. I don't see much offset between
the two in the areas I checked but I know it varies. If you have to use
both for some reason, just align the Mapbox imagery with the buildings
drawn using the Bing imagery before you trace.
In iD use the "Background settings" tab on the right (looks like 3
stacked sheets of paper) and at the bottom it says "Align Imagery" and
clicking that gives you four arrows to move the layer around.
2. & 3. - If it looks like a structure, please map it :) Some structures
that are significant can be very small, latrines and meat drying shacks
for example are pretty tiny, but significant. So if you think it is a
structure, just map it.
Even if it is just an animal run-in shed, in some situations when people
are on the ground trying to find their way, they will be looking for any
landmark they can find on a map to match up with what they are looking
at on the ground so it helps in those situations too.
Welcome aboard and thank you very much for asking, please ask anything
else that comes to mind, we are always happy to answer questions and if
you have the question, other people do too so it helps everyone.
Cheers,
Blake

I'm new to HOT/OSM projects and am working on the Swaziland Task as my
intro project.
Three questions so far:
1. Should I be using Bing Imagery? (Fairly significant offset from
Mapbox imagery.)
2. Is there a minimum size of building to map? I've seen some things
that may be very small sheds, but I can't really confirm that based on
the imagery.
3. When in doubt, should I map it as a building or leave it out? I
realize there will be a review.
Thanks- German
