For anyone who has never installed, customized, patched, or administrated an internet forum, it's hard to describe the piece of crap that vBulletin has become. 4.x is FAR worse, and they're gradually dropping support for 3.x, which is what WDWmagic was previously running.
This software vs vBulletin is like comparing Google Chrome to Internet Explorer.....a million times simpler, less code, easier to customize, follows actual internet coding standards, and is in tune with today's "social" internet.
I'm very excited for this new endeavor. It will take us all some getting used to it (and I've learned that I need to re-visit all my subscribed threads to start getting the emails again), but once Steve has a chance to make some more modifications to the style, and everyone gets their undies out of a wad, I predict a much more user-friendly forum that all will enjoy.
