This is also a sad way for a forum, indeed a whole website that used to help patients to die. From some correspondence is that become clear to me that the IT person in charge of the database migration and web design is not up to the task. So the only way to fix the problem is to bring in someone else to do the job.

I might write a letter with another long time user to the owner and ceo of the charity that runs the site. She has a longer relationship with the site and the Dr. who runs it. I've asked her (on a different forum) if she wants to go in on a letter with me.

If she says yes then I'll do it and if no, then the site will die a long slow death. Every user who encounters it now will just be repulsed by the mess and all the broken links so the longer they leave their 'bright shiny' new site up the more damage they do to themselves.
