In the current version, only DailyRoads.com is a valid upload server. The username and password are auto-generated when the application first runs, so you are not required to register first. However, you can change the username and password on the server, and specify them in the application, too.
Upload photos and videos - check what kind of files to automatically upload to this server. This works in conjunction with the upload options for Video and Photo settings. Until further upload servers are available, it is recommended to leave these options checked, and control photo/video upload from their respective settings.
Visibility on server - choose how you want your uploaded files to be displayed on the server, i.e. who can see your uploads (you, your friends, or everybody).
