The old JSesh web site used Drupal 5, which is a nice software, as its basis. Unfortunately, Drupal's current version is now 8, and upgrade from 5 to 8 is quite costly.
For safety reasons, I have decided to use a simpler software, called Grav, instead of Drupal. In the processed, I have removed the forums, which were not very active anyway - I have kept their archives, and they will be available online soon.
For questions and suggestions, I would suggest to use e-mail. See the address in the contact section on the site home page.
