+ID can be either a bug id, or blank/"DIR", in which case it refers to the

+
+SERVERS specifies the servers from which you would like to receive
+notification. Multiple severs may be specified in a comma-separated
+list, or you can use "*" to match all servers (the default). If you
+have not selected a server, it should politely refrain from notifying
+you of changes, although there is no way to guarantee this behavior.
+
+Available TYPES:
+ For bugs: all
+ For DIR : all
+ new - only notify when new bugs are added
+
+For unsubscription, any listed SERVERS and TYPES are removed from your
+subscription. Either the catch-all server "*" or type "all" will
+remove SUBSCRIBER entirely from the specified ID.
+
+This command is intended for use primarily by public interfaces, since
+if you're just hacking away on your private repository, you'll known
+what's changed ;). This command just (un)sets the appropriate
+subscriptions, and leaves it up to each interface to perform the
+notification.
