Thanks brogan, unfortunately none of those are an option for me. I installed this add-on, however, it requires you specify a string and then moves all threads that contain that string in the thread title. Can you think of a string that would essentially specify all threads? I know this is a third party add-on, but I figure if anyone can think of it, it'll be you (the developer hasn't been active since June so I can't ask him).
I'm in the process of developing an entirely new site on xF1.4 rather than updating the existing one due to a variety of issues (we haven't purchased a renewed license yet so it's behind a .htaccess password). However, there is a variety of custom code we've used to modify templates, add-ons, etc., to give the site the functionality we require so it's a long process and we're trying to streamline the existing forum in the meantime.
