The Server Settings page allows you to configure miscellaneous server settings such as the path where repositories will be stored, email settings, etc.
This allows you to specify the location where Subversion is installed. This is set during first-time configuration so you shouldn’t have to change this unless you change your Subversion install.

The Repository Path is the location where your repositories will be stored on the server. If you have installed Sublime on the C drive, but want to store your repositories on another drive with more space, you can change this path.
Note: changing this path does NOT automatically move repositories. You must do that manually by copying the complete repository folders to the new location.
The Repository Access URL is the URL that users will connect to when accessing subversion repositories. By default this will be the name of your server, but you can change this if you have configured DNS with a friendly name for your server. See also Advanced Website Configuration.

The New Repository Message is simply the log entry that will be created for each new repository. It can be any text you like.

The Email Settings section allows you to configure how outgoing email messages will be sent. This section must be configured for commit notifications to be sent.
