TeX support on edaboard seems to have been broken for quite a long time. I believe it has been about a year now. Is there a plan to get it fixed?
For me, it is particularly frustrating that my blog is broken because I use my own blog posts (such as this one: link) as a quick reference for my own work. That blog post also has 20,000+ views and it seems a shame that people will go there and see nothing but "elektroda.pl" everywhere.
