Should I make this forum?

[Omniscient]

People thing that what I did I always did. They make immitation HF or Mybb Central sites every week now. I didn't charge for subscriptions on either site until they were established as viable sites with a reputation. You should never start a site and ask people to pay to be part of it until it's something they "must-have".

I haven't seen your work but it sounds like you're coming from a place with little to zero experience. Spend a year making themes and offering support at MyBBoard.net then consider if you want to begin commercial work.
