[HOT] Worried about task 1018

I think I'm moderately experienced in mapping.  In West Africa I'm very
comfortable validating, in Nepal I'm happy I know what a building looks
like but paths, streams etc I'm not so comfortable with, there is a lot of
distracting detail on the images.  Do I validate and clean up the building
and tag side?  Or just add a few more buildings?

Thoughts?

Thanks John
