phpbb con joomla

[Il_Piovra]

Eccovi subito la mia richesta:
ho fatto il bridge tra joomla e phpbb ma come faccio a far visuazizzare il forum al 100% della larghezza del sito? mi rimane sempre la barra laterale nonostante tolga tutti i bottoni.
Questo è il link del sito: http://www.italianpokersuite.it/forum/
Mi aiutate per favore? grazie.

Questo è il codice css del template di joomla:
