URL Options

Character Length
Set the maximum length of plugin-generated URLs. This does not include your domain, nor does it include the subdirectory (if you set that option below). The default length is 8.
Subdirectory
Optionally set a subdirectory that all URLs will be created under (i.e., http://yourblog.com/go/ -- enter /go in the field above, no trailing slash).
Redirect Type
Set the type of redirect (301 or 302) that Link Shortcut uses.
