I have upgraded the forum component of the site and, on quick run-through, all appears well. If you see something amiss, let me know ASAP.
One of the benefits of the upgrade was a more responsive template out-of-the-box. This saves me doing a more elegant template since the main complaint people have (Nadav aside) is the general suckiness on mobile devices. Now, it sucks less. I have also temporarily disabled some of the sidebar stuff to further help with the layout, but I will be putting those back in when I can. Clearly the "Reading List", in particular, generates interest and discussion.
