[OSM-talk] tutorial for mapping buildings?

[john whelan]

Not all the problem buildings are HOT related I think it would be of more
general use but given HOT's fascination with buildings currently many of
the new mappers are theirs.

We also seem to have an increase in the number of duplicate buildings
lately but that is another issue and not too difficult to correct other
than the sheer numbers of them.
