You are not a technical person, but you are the one creating the place. So it’s up to you to create examples of what you expect to happen there.
At the moment, it’s a bit like an empty field. You’ve created the field and put one thing in it, but people don’t yet know what you’re hoping will be built there. You probably have to start building a little of it yourself — not necessarily because you have all the answers, but to give people an idea of what kind of place this is supposed to become.
So I think the question to ask is: Why would someone want to join your forum?
