[Haskell-cafe] Haskell Weekly

Thu Jun 1 23:07:31 UTC 2017

Sorry about that! Apparently I mis-configured some part of my MailChimp
account. You should now be able to request plain text emails by clicking
the "update your preferences" link in the footer of any Haskell Weekly
email. I can't guarantee that it'll look as nice as what I provided, but
hopefully it's better than what you're dealing with now.
