The good folks at freeforums.org, in December 2016 took it upon themselves
to do some sort of major revamp of their system, including moving to new servers.
Unfortunately, it has not gone very smoothly, with lots of downtime and fits and starts.
Here is the status as best as I can report it:
Our forum is back online, but attachments to old posts do not appear.
I hope that problem is eventually resolved.
There is no status information available from them, since their
support pages are not working at all today.
As the situation evolves, I will update this post.
The support pages are now working; the attachments are still missing.
Apparently attachments are on a different server, and they are having problems with it.
