pitscheplatsch,
Do you have any idea when edits "fully update"?  I have edited the "old" trails to delete/modify sections.
I also imported and then traced the current/new trail segments. I'm just not 100% certain I've done it all correctly.  The traced segments are not showing up when I go to OSM.  I was kind of assuming it takes a day or so, but this is my first time using OSM so I'm trying to catch up.
