Commit in docs/usefor (usepro.xml)

    Date: Monday, May 25, 2009 @ 17:31:32
  Author: eagle
Revision: 5927

Add multiple minor typo fixes and clarifications.

Examples showing newsgroup description information now include a specific
note saying that the spaces are typographic and that in real messages
tabs are required.  Checkgroups update moderation status as well.
