I came to vBulletin when the people at UBBDev.com decided to abuse me away from there. Because they lacked the people skills and general kindness to run a proper modification forum - instead abused, degenerated members, and so forth.
Shows how much the support forums can persuade a person to stay with something or not. Maybe they've learnt their lesson these days and dropped their egotistical approach to running a forum. It wasn't so much the admins, they were great people, but the moderators they chose. *makes choking noises*
At that point I stopped using BBS, then I became an admin on a vBulletin forum and it went on from there.
That sounds really mean, but, that's how I came to vBulletin. (Plus it's better

)
