After a decade of running the forum pretty much unchanged I decided to try an experiment and see how using a Facebook group goes.
If you are not already logged into Facebook you will need to log in (or create a Facebook account)
when you get redirected to the MerrimackForum.org Facebook group page.
If the redirect doesn't work, try https://www.facebook.com/groups/merrimackforum/.
A read only version of the old forum can be found at http://www.merrimackforum.org/phpBB3forum/
You can read the Facebook group (but can't post) at this link http://www.wallflux.com/info/411739005552475
