Thanks, Hawk. I don't remember the one you specifically mentioned. However, if they are not here now, they possibly will not return. It may have been an add-on that is not compatible with this version of the software, but I can't be sure.
Hawk53 I think you are asking about the sorting functions that used to be down below the forum.
It now shows up as the "filter" tool above the forum on the right. I think it is a better tool for the purpose. The attribute ordering of threads in the forum is in the "order" drop down at the bottom of the filter form.
