Lots!

- A bunch of the SIG-level functionality is not fully implemented.  We need
  invites, some admin functions, and the "Manage" button on the "top
  content" window to work.

- Should we provide the sysadmin the ability to disable SIG creation for
  non-admin users?  Maybe there needs to be a "global" set of levels that
  aren't hardcoded.  Where do they get stored?  The database?  (Maybe the
  nice shiny new "globals" table?)

- There's no system admin functionality AT ALL.  We need to have this stuff
  before we go live.  (It plugs into the Administrative SIG features.)

- Unimplemented functions on the Top page:
  Manage SIG list (SIG sidebox)
  Manage Conference Hotlist (Conference sidebox)
  Customize Sideboxes

- The plan for the "main" part of the Top page is to let a sysadmin put
  notices there by "publishing" selected conference messages to the front page.
  We may include a welcome message up top to be displayed if the user's not
  logged in.

- Implement quick e-mail from the user profile display (engine support and
  UI).

- More SELECT queries that specify discrete columns need to start using
  numeric indexes to retrieve the column data, instead of names.  This will
  make the retrieval process more efficient, and make for shorter SQL
  statements in the case of joined queries (no need to SELECT table.column
  AS name).

- Slippage during posting is still untested.

- We need a "manage" button at conference list level so we can use that to
  manage the ordering of conferences.  This operation should be accessible
  only to users with "create" privilege on the SIG.

- Conference hotlist is now partially implemented, but we need some more work
  at engine level.

- Not everybody likes purple.  Provide a way to change the default colors.
  Probably via entries in render-config.xml.  Of course, if we go to a
  different rendering system eventually, we won't need this.

- Javadocs.  Lots of javadocs.

- I haven't explored the possibility of using Tomcat-Apache integration yet.
  This is something I'd like to explore one day.  We may need it for EMinds.
  Actually, we probably will.

- Continue pressing on.  "Failure is not an option."
