Hi,
the searches on the gretl mailing lists are done / handed over to
Google. Some time (weeks/months?) ago Google changed its terms of
service, and as a side effect requires explicit acceptance. So anybody
who does not accept their terms of service is not able anymore to search
on the gretl mailing lists.
I suspect that the reaction of some people is that they don't understand
why one would decline Google's terms. On the other hand there are also
people that don't see why some software should be free (as in speech) if
Stata (or Eviews, or whatever) already provide (some of) the
functionality...
cheers,
sven
