Not sure I completely understood you but if you wanted to make a page as the homepage when someone types the name of your forum, go to your Acp->Basic Board Information->Index Page Route and replace the /forums there with pages/pagename/Hi,
I have xenforo and everything set up. I want it so when people go onto my website, there at the homepage NOT forums. And, when I create a page in xenforo, I don't want people to what is on it at the forums tab. It shows it where my page name is.
No please, no nothing, but straight to demanding, are we?
Are you using XenPorta? If so then you should post your questions/problems in the discussion thread for that resource. I'd suggest you look through the thread too as your question is likely to have already been answered.
