MyBB Community Forums

I recently took ownership of an existing MyBB Forum version 1.6.3. Although I am an administrator, I cannot see the "inc" folder or the config.php file. I need to know how to make myself the super-administrator on the site and revoke that privileged from the previous owner.

Can I just change her user group to something else to make me become the super administrator?

Thanks for all the help and sorry I am extremely new to all of this.

How can you not see the inc folder?

I was misinformed as to where the inc folder was located. I was looking under the Admin Panel, not on my host where MyBB is installed.
