I downloaded the mybb file but i was wondering if i got to make the website an separate software or if there is a place where i can make it on the net like iclanwebsite
You can develop your frontend (website) with whatever software you want, but keep in mind you will have to bridge it to centralize the users to your forum.
I would upload your mybb into your root and then tweak your portal.php page to make it your "frontend".
Is there a way of accessing it with mybb
