@cindex group buffer
+@c Alex Schroeder suggests to rearrange this as follows:
+@c
+@c <kensanata> ok, just save it for reference. I'll go to bed in a minute.
+@c 1. Selecting a Group, 2. (new) Finding a Group, 3. Group Levels,
+@c 4. Subscription Commands, 5. Group Maneuvering, 6. Group Data,
+@c 7. Group Score, 8. Group Buffer Format
+@c <kensanata> Group Levels should have more information on levels 5 to 9. I
+@c suggest to split the 4th paragraph ("Gnus considers groups...") as follows:
+@c <kensanata> First, "Gnus considers groups... (default 9)."
+@c <kensanata> New, a table summarizing what levels 1 to 9 mean.
+@c <kensanata> Third, "Gnus treats subscribed ... reasons of efficiency"
+@c <kensanata> Then expand the next paragraph or add some more to it.
+@c This short one sentence explains levels 1 and 2, therefore I understand
+@c that I should keep important news at 3 and boring news at 4.
+@c Say so! Then go on to explain why I should bother with levels 6 to 9.
+@c Maybe keep those that you don't want to read temporarily at 6,
+@c those that you never want to read at 8, those that offend your
+@c human rights at 9...
