I'd like to have 3 lines for address with moderncv style. So I've added this lines in my file
\makeatletter
\renewcommand*{\address}[3]{\def\@addressstreet{#1}\def\@addresscity{#2}\def\@addresscountry{#3}}
\makeatother
\address{Street }{town}{Country}
but nothing has changed. Can anybody tell me how can I do?
