On the World-Wide Web, there are several URLs of likely interest:
We run two mailing lists about Glasgow Haskell. We encourage you to join, as you feel is appropriate.
This list is for GHC users to chat among themselves. Subscription can be done on-line at http://www.haskell.org/mailman/listinfo/glasgow-haskell-users.
To communicate with your fellow users, send mail to <glasgow-haskell-users@haskell.org>.
To contact the list administrator, send mail to <glasgow-haskell-users-admin@haskell.org>. An archive of the list is available at http://www.haskell.org/pipermail/glasgow-haskell-users/.
Send bug reports for GHC to this address! The sad and lonely people who subscribe to this list will muse upon what's wrong and what you might do about it.
Subscription can be done on-line at http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs.
Again, you may contact the list administrator at <glasgow-haskell-bugs-admin@haskell.org>. And, yes, an archive of the list is available on the Web at the http://www.haskell.org/pipermail/glasgow-haskell-bugs/.
The hardcore GHC developers hang out here. This list also gets commit message from the CVS repository. There are several other similar lists for other parts of the CVS repository (eg. cvs-hslibs, cvs-happy, cvs-hdirect etc.)
To subscribe: http://www.haskell.org/mailman/listinfo/cvs-ghc
There are several other haskell and GHC-related mailing lists served by www.haskell.org. Go to http://www.haskell.org/mailman/listinfo/ for the full list.
Some Haskell-related discussion also takes place in the Usenet newsgroup comp.lang.functional.
