[OSM-newbies] Interior ring with Potlatch?

[David Fawcett]

I just added a building outline using Potlatch and drew a second area
polygon to delineate an open area in the building.  I am not sure how
to tie this second polygon to the first one to create the interior
ring in the polygon.  When I drew them, I went clockwise with the
exterior ring and counter-clockwise with the interior ring. I am not
sure if this makes any difference.  Google didn't turn up any good
answers.

The building is at:

Thanks,

David.
