When opening the list of previous routes on the map editor, I'd suggest the following:

• keep routes available up to a certain limit, ideally one year (like for example foursquare does with the checkins). More than one year may be too much data on the servers, but less than one year would be too short to look at older routes.
• routes available on the editor should really be available. currently old routes are visible on the list, but then fails to load with a "permission denied". I can't understand if there's a time limit, or if the routes stop working after a mapdate (last mandate was at Aug 5th and the routes stopped working at Aug 7th evening).
• as editing permissions are available up to 3 month, the routes shall clearly be available at least those 3 month, ideally the suggested year.
• routes dropping after one-two months are unacceptable because a mapdate itself takes one-two months, so when the map goes in, we can't look at old routes to have an idea if the fixes were correctly done
• if the routes are not available for whatever reason (a DB schema change that screws the route is acceptable), they shall not be visible on the editor list.
• it would be nice to be able to delete routes from the list.
• it would be nice to download the routes from the list, either on the current wfs format, or in other formats (kml for example)
