Yes, the dpreview closing shocked us all. As you know I also setup a dpreview clone, in case people are interested in at
https://dpreview.communitydummy.com so nobody gets lost in the horror-scenario. I am doing community forum management since 2002 and know, that this is not as easy as many think it is, to survive longterm.
But people who search a brand specific forum, will prefer fujicommunity.com or other similar alternatives. There are so many alternatives out there, that every pot will find its lid.
I think the big advante of our Fuji community is, that it is relatively new and all dpreview users can still influence how it should look like. This is a really good way to build the community as times goes on.
Also we use IMHO the best forum software out there. and I tried them all over the last 20 years. That makes a huge difference as a user, most people are not aware of at the beginning.
