ETA: The YW Discussion Forums are up again after their upgrade to vBulletin 4.2.4.
Unfortunately the upgrade meant that some of our plugins became nonfunctional, and/or broke the site, so it took several days longer than expected to debug the installation so it would work again. One loss during this process, as it happens, was the fabled Post Thank You Hack which allowed users to thank each other for postings. It had to be removed so that pages would load correctly. [Or at all.] I’m hoping it’ll be updated for the new vBulletin version: we’ll see what happens.
Meanwhile: back to business as usual, and thank you for your patience.
