rac.misc is the catch-all group at the end of the RAC* hierarchy.
Miscellaneous does NOT mean "everything", it means "everything else".
Anything that doesn't fit in any of the other groups goes here. What does
* Industry -- publishing, distribution, retail, "getting started", etc.
* Creators -- general discussion of a writer/artist/etc's work
* Comics with no subgroup -- most titles from Image, Dark Horse,
Acclaim/Valiant, Antarctic, Paradox, Helix, Archie, Disney, etc.
* Anything Else -- art styles, comics & computers, awards, essays, etc.
