PS: It took me a while to find this mailing list, is it on purpose that the
mailing list is not mentioned on haiku-os.org, or maybe deeply hidden in the
site?
You are right, and there is no good reason (that I know of) for "hiding"
the existence of this mailing list on the project website. I will write
to the webmaster now and ask him to consider adding links in the
appropriate places. It can't hurt to ask...
