what is?!

Thise are bitwiise operators. They hold mutiable settings in one database field. I wouldn't mess with anything in init.php unless you know what your doing. init.php is the core of your forum.

notice those are multiplication of number 2 (2^x).
it's quite handy method/algorithm of storing into 1 field a single number that represents several options selection in it, and then know which of them were checked ;)

Indeed, init.php and config.php are the core files of your vB.
