5.) vbPortal/vBulletin header-inc.php Visual Integration
If you use vbPortal or vBulletin, you can integrate your forum's look and feel into ReviewPost. The vbPortal integration displays your vbPortal top/left side, and bottom, around ReviewPost. The vBulletin integration displays your default vB header/footer templates with ReviewPost. To implement this, open header-inc.php and follow the instructions there.
There are no instructions to follow in header-inc.php.
