can anyone tell me how to get one or created one?
Main site?
You mean like a homepage? What do you want on it?
This doesn't really have much to do with MyBB. It's more general web design/development.
Yeah like I said, this doesn't have a lot to do with MyBB. These are support forums for MyBB itself and MyBB related things. A homepage has nothing to do with MyBB - at least not in the way that you're asking.
May I suggest Google?
The
User Submitted Tutorials might be a good start too. Some threads explain how to integrate your forum into a homepage/website.
