Hi, I run www.gyancentral.com/forum which is a community for students in India. I lot of students have pointed out that they need niche forums for example "students of law" want a law niche forum and "students of engineering" want an engineering niche forum. I was thinking of creating two forums on www.gyancentral.com/law/forum and www.gyancentral.com/engineering/forum for the students. The following are my queries: 1. Would i need separate Vbulletin and VBSEO licenses for the same? 2. Is it advisable to run two Vbulletin instances on the same domain?
