tehste, the plugin system will not make vB.org go anywhere but up. Here is the past/present/future for vB.org....
2000 vB.com is hosting hacks....
2001 vB.org opens with vBulletin 2 hacks (all hacks from vb.com transfered to vb.org)
2004 vB.org allows vB3.0 hack releases
2005 vB.org allows vB3.5 Beta Hacks to be released.
2008 vB.org allows vB4.0 Beta Hacks to be released
2020 vB.org allows vB5.0 Beta Hacks to be released
You see a pattern yet? vB.org is for hacks.

vB.com is just for the default software. If your having a problem with the default features of vBulletin and all your plugins are DISABLED then you would go to vB.com. If the problem only happens when your plugins are turned on, then you would narrow down which one it is, and ask for support here at vB.org. (The hack thread)
