Hi Manuel,
That's why I'm asking if I'm allowed to just register a project at
savannah to get a high quality mailing list?
It's never come up before. It hasn't been discussed explicitly among
the current savannah admins, but I think the answer is no, sorry.
The purpose of savannah is ultimately to promote free software, per the
various items on https://savannah.gnu.org/register/requirements.php.
When the software is hosted somewhere else, it makes little sense for
savannah to just provide mailing lists, as far as I can see.
Best regards,
Karl
