I will revert the changeset later today when I have access to JOSM to do so easily.

I may have answered my own question. It looks like there is a "Reverter Plugin" for JOSM. I don't have access to JOSM on this computer, but can later today.

Ok, I don't have a problem doing this, I understand what you are saying. What is the easiest way to revert an entire changeset without going back through and undoing the edits 1 by 1?
