Ciao, <br/><br/>I've found in several places the expression: <br/><br/>"It allows to do something" <br/><br/>But is it correct? <br/>Or should it be: <br/><br/>"It allows one to do something" <br/><br/>or <br/><br/>"It allows doing something" <br/><br/>Which is the correct expression? <br/><br/>Thanks, <br/><br/>Stefano
