Ftp'in

Can more than one person ftp a website or other ftp'able application at the one time?

As I'm getting the "No connection could be made because the target machine actively refused it. Connection closed."

but all my details are correct and I'm thinking maybe one of my family are ftp'ing. Should I still be able to connect if someone else is?

it depends on the server configuration whether more than one connection for a certain user is allowed, usually this is no problem. the error message you're quoting means something different anyways: there is no ftp service at all running at the machine you're trying to connect to. please post the connection log here in order to be able to help you.
