Personal information

This is general information about yourself. The nick is required, though it's suggested that you pick the correct upload line speed value as well.

Nick: This nickname, or handle, will identify you when you join a hub. It can be overridden on a per-hub basis in the Favorite Hub Properties.
Description: This description will show in the user list. It can be overridden on a per-hub basis in the Favorite Hub Properties.
Email: This field is for sharing your email address, if you wish it. It can be overridden on a per-hub basis in the Favorite Hub Properties.
Line speed (upload): This drop-down contains a number of common upload speeds (in MiB/s), please choose the one closest to your own. Do not put in your download speed; this setting is a measure of how fast a source you are likely to be for other users. This value will be shown for the users on NMDC hubs only.

Away mode

These settings control the away mode. It is a mode that DC++ can be switched to to signify that you are away from DC++ and unavailable at the time. This mode can be manually activated by using the Away indicator in the status bar of the main window or the /away <message> and /back chat commands. It can also be automatically activated according to the settings below.

Away message (empty = no away message): This defines the default away message. An away message is a message that is automatically sent back as a response to private messages received by DC++ while it is in away mode. All time formatting variables are available, see Logs. Use Ctrl + Enter to create a new line. When this field is empty, no default away message is set. Note that this default message can be overridden by specifying a custom message with the /away <message> chat command.
Enable away mode when DC++ is minimized: Switch to away mode whenever the DC++ window is minimized in the Windows taskbar or in the notification area; disable away mode when the DC++ window is restored.
Enable away mode when the Windows session is locked: Switch to away mode whenever the Windows session is locked (generally by Windows key + L or via Ctrl + Alt + Del); disable away mode when the Windows session is unlocked.
Add timestamp to end of away messages: Display time at which DC++ entered away mode in away message.
Enable away mode after X minutes of inactivity: Switch to away mode whenever the Windows session hasn't received any mouse or keyboard input for the last X minutes; disable away mode when input is received again. Set to 0 to disable this functionality. The default value is 10 minutes.
