[OS X Emacs] How to report bugs on the nightly build

[Dagnat Fabien]

Hello,
I tend to use the nightly build. The last version downloaded yesterday crash on my machine when I open it. 
I checked on the webpage where to send the crash report but the page invite to send a mail to a specific mailing list and does not contain its address. There is a link to the mailing archive where I don't have access and it suggests to use the builtin function which does not work for me as aquamacs crash systematically on startup.
