This is by far the most radically hacked IPB I have seen. I was wondering, do you keep a list of all the hacks you install? If so, you should have it somewhere on the site, as I am sure many people would be interested as I am in what hacks you have installed. There is a hack over at IBPlanet that allows you to have a official hacks list, and add/remove entries via the admin panel. I see many interesting modifications on the boards here that i would like to know the name of so i could implement them into my own board.
BTW, I dont suppose you will be upgrading to IPB 2.0, at least until there are plenty of mods to choose from. Although IPB 2.0 is going to have tons of cool new features, I cant see having to everthing right away. IPB 1.3 is good too!
