This site

  • This site is a combined online help and bug tracking system for JOSM and JOSM plugins.
  • No login is required to use this site (neither for reading nor for changes to wiki or bug tracker).
  • A login has the following advantages:
    • The JOSM applet can store settings on the server.
    • Mail is sent for changes in your own bug tracker tickets. This is possible by entering an e-mail as user name in the tickets, too, but then be aware that the address is openly visible and you are unable to change that later.
    • Page settings are remembered (e.g. input field size and a lot of other stuff).
  • Logins which have no e-mail address or which have not been used at least once are automatically deleted.
  • Logins to edit the OpenStreetMap database are separate from the logins on this server.
  • The secured HTTPS version of this site uses a SSL certificate? with the SHA1 fingerprint C5:8A:CF:54:15:7D:37:1F:21:6D:5D:92:B4:B4:FA:3A:3C:AA:14:6C.
