Inside-a zee-a zip, yuou vill feend three-a text feeles:

Zee-a furst step is tu insert zee-a cuntents ouff fuon_ffeelters.php.txt it zee-a ind ouff yuour b2-incluodes/b2ffuonctiuns.php feele-a (buot beffure-a zee-a feenel ‘?>‘ leene-a)

    idd_ffeelter('ill', 'vptextuorize-a');

Juost beffure zeet leene-a, insert zee-a cuntents ouff zee-a ectifete_ffeelters.php.txt feele-a. Vit zees cude-a in plece-a, yuour blug vill ouotumeticelly svitch oun zee-a purete-a feelter oun Telk LEEke-a a Purete-a Dey (September 19). Ilsu, uny ouff zee-a ouzeer feelters cuon be-a ictifeted by iddeeng ‘?feelter=feelterneme‘ tu zee-a ind ouff yuour URL (vhere-a feelterneme is oune-a ouff ‘purete‘, ‘cheff‘, ‘fuodd‘, ‘jeefe‘, our ‘kruot‘). Bork Bork Bork!

Zees sterted vhee-a I idded a purete-a feelter tu my blug fur Telk LEEke-a a Purete-a Dey. My furst fersiun ves iesier thuon I ixpected it tu be-a (thuough it hed flevs), vheech inspured me-a tu lucete-a und cunfert sume-a ouff Kelsey’s MufebleJEEfe-a feelters. Bork Bork Bork!
