Hi. The link to the mailing list on the GHC page is not correct. It should link to http://www.haskell.org/ghc/docs/latest/html/users_guide/mailing-lists-GHC.html instead of http://www.haskell.org/ghc/docs/latest/html/users_guide/introduction-GHC.html#mailing-lists-GHC . Greetings. -- marcot http://marcot.iaaeee.org/
