Valutazione Template - Joomla! Forum - community, help and support

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!
