not really, no one could actually do the ranking system given there are over 40,000 members. the closest thing there is to a ranking system are the titles given by your post count.
Well after searching, for quite some time, for a good fitting mod for our forum base, I came up a little dry. So, in addition to searching for a solid quiz base that I may just add data to, I'm also building my own that should integrrate into vB nicely. What I'd really like to do though is download a base and then add a little code to it. Something that will be quite easy for the admin here at TF to maintain later on.
But in short, yes I'm working on it. That and trying to fill in flight time so that I can finally get my license. (Which has been taking some priority lately)
