I think the link being on this page says a lot about the
movement: http://www.roundcube.net/?p=forum.
Its authenticity cannot be denied as it’s listed at the top of the
page. I think in order to gain an idea of the scope of the movement we
need to ask a different question: do people intend to continue using the
mailing list as actively as before the forums sprung up?
I’ve noticed that the mailing list is fully moderated,
(please correct me if I’m wrong). Sometimes posts do not show up for a
few hours if at all. I made a post to this list recently that never
appeared. I’ve noticed that some days, there are no posts to the list at
all and then a flood of them pours in the next day as the moderator was able to
find the time to approve everything. In a forum, while moderated, posts show up
immediately and can only be removed as someone with moderation privileges finds
the time to check the forums.
There are obviously heavy pros and cons on both forums and
mailing list. It is nice to be able to direct a mail to the general
community and the core developers and expect that those people will at least
see the subject line in their email headers. A post made to a forum could
be missed as it cascades down the page for a couple of days. Intuition
can only imply that the mailing list will remain an integral part in the
communication of the development community and user base as long as it
continues to be hosted.
