+
+LOCAL_CHANNELS
+ * Type: boolean
+ * Default: TRUE
+
+If set, allow users to create local channels.
+
+TOPIC_BURST
+ * Type: boolean
+ * Default: FALSE
+
+If set, send the current topic value and timestamp for channels during
+burst. This generally only makes sense for hubs to use, and it causes
+a large increase in net.burst size.
+
+CHANNELLEN
+ * Type: integer
+ * Default: 200
+
+This is the allowed length of locally created channels. It may not be
+larger than the CHANNELLEN #define. Like the NICKLEN feature, this is
+intended to ease changes in channel name length across a network.
+
+OPLEVELS
+ * Type: boolean
+ * Default: TRUE
+
+This allows local users to set the +A and +U modes (admin and user
+passwords, respectively) on channels where they are marked as channel
+managers. This feature must be disabled until all servers on the
+network are able to interpret and handle these modes correctly.
+
+ZANNELS
+ * Type: boolean
+ * Default: TRUE
+
+This preserves empty channels with no admin password so that it is
+impractical to become the channel manager by clearing out the channel.
+It must be set to FALSE if there are both 2.10.11.x servers and
+2.10.12.y servers on the network where y < 4. It should be set to
+TRUE whenever the OPLEVELS features is TRUE.
