The main change will be that we will be running vBulletin 3, which you can try at
http://www.vbulletin.com, instead of vBulletin 2. We may lose a few hacks in the update (the store hack, for example), though that is still uncertain. We will have to update the current themes to work with vB3, so you should expect a new look for the forums. Finally, we will get a new portal, or code our own front page for the new version of vB. As you might expect, this will take some time, so please be patient. Until we have everything working, you can continue to use the vB2 forums, which should remain unaffected.
