OpenStreetMap
Found deleted Roundabouts in the Area i was mapping exclusively for the last weeks. After i put them in again i found more bogus edits tonight. Foot/Cycle/Waterways which are definitly not there. Footways without any connection although i know there is one etc.
The user seems to just map from memory and using potlatch. He is not really carful doing edits and i already tidied up a bit by deleting points and ways without any tags and connections etc.
Now i'd like to contact that user but there seem to not be any standard way to map a username to an e-mail address

You can find out who created a Way in JOSM (and it can't be anonynmous because Potlatch doesn't allow anonymous users) - download the offending area, select an offending way and the user name shows up in the appropriate panel. You can then contact the user through the messaging facility at osm.org/user/ (remembering to replace anty spaces in the name with %20)

There us a special user plugin that will take you to the user page of the user who made the last edit.
