Nearly 2 decades ago, vBulletin used to be the best forum software around. Until they were bought by Internet Brands in 2007, whose only interest is money.
In the following 3 to 4 years, Internet Brands drove vBulletin to the ground. They lost their employees, and their new releases were all absolute shit. Even today, vBulletin 5 is one hell of a stinker. Stay away from it.
Then around 2011, everybody moved their forums to XenForo and never looked back. vBulletin was becoming a thing of the past.
For some reason, something made me think of vBulletin today, so I decided to take a look at their official forum and their modding community, vB.org. Oh boy, the years haven't been kind to them. These sites are basically dead now.
