FWIW, it's a few years later -- I was able to log in via elinks (a lynx variant used by one of our members), and though the interface was a little messy it worked. Search seemed to not work (or I wasn't using it right), but I could browse. Writing a reply to a post seemed impossible though, as I got "403 forbidden." Have not tried with JAWS or the like yet. I'm not sure if this is on the roadmap to change but here is a quick note that these are the results as of June 2018.
