If you have questions reagrding default vBulletin vBulletin.com, the official company website, is the place to go. This goes for licensing issues, installation questions or support. To receive private technical or sales support the ticket system is also available either from the vBulletin.com Members' Area or by sending a mail to
sales@vbulletin.com or
support@vbulletin.com.
For free available resources beyond the default package, styles/skins or modifications and community support on these, vBulletin.org is the place to go. You will find most using the tabbed section in the top of each page. All the resources available on vBulletin.org are stricktly free of charge.
If you want to purchase styles or modifications then you will need to go to external websites as the official websites do not deal with third party commercial issues.
