vBulletin.com is the offical Jelsoft website for downloading and getting complete and full support from the true developers and support team of vBulletin. vBulletin.org is also a Jelsoft sponsered website, but instead of full-on support, it provides modifications for the vBulletin software, while it's developers join here, but are not required to remain active. All Black/Bold names are staff on vbulletin.com. The official developers of vBulletin aren't required to even bother with this website, though it does help as it's the official resource site. And to answer your first question, no. vBulletin developers mainly work with the actualy files, though some of them have developed hacks, and add-ons for vBulletin.
