- 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:
- 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.
