I just started working with Potlatch 2 this morning. I had previously been using Mapzen and when you saved the data with Mapzen, it was considered a completed change set.
I assumed, insert phrase about assuming here, that Potlatch worked similarly to Mapzen in this aspect, but when I looked at my edit history, I now have a changeset (6737444) that covers an extremely large area and does not have the correct changeset comment.
Even worse, my browser crashed and the changeset is still showing as "still editing".
Question 1: How do you close out a changeset and start a new changeset in Potlatch 2?
Question 2: Can anyone delete/revert my changeset #6737444? The areas I was mapping are fairly remote and it is unlikely that anyone has made any changes to my changes as of 12/22/10.
Revised: The changeset finally timed out and closed itself. I would still like to delete/revert the changeset to allow me to give better comments to each specific change (i.e. source, etc).
Recently you can type 'C' to close the changeset.
