[rt-users] Error in "RT Essentials" book.

[Joby Walker]

It is an error but the two statements in the book are equivalent:

pg 88

if ($Transaction->CreatorObj->id != $RT::Nobody->id){}

pg 89

unless ($Transaction->CreatorObj->id == $RT::Nobody->id){}


Different ways to check for the same negative; "if this is not true" vs.
"unless this is true".
