[Haskell] Security problem of email registration page

Hi there, I become aware of the problem that https://mail.haskell.org/mailman/listinfo/haskell send a password to http://mail.haskell.org/cgi-bin/mailman/subscribe/haskell. Probably it means this page will send a password without encryption. Could you use https instead of http, or remove this duplicate page? I had used https://mail.haskell.org/cgi-bin/mailman/listinfo/haskell instead.
