Sympatico consists of several regional Canadian web servers, each distinct, but probably very similar in set up. We recently helped a new user to get CSB configured to work with Sympatico. As usual, once we got the correct "settings", it worked like a charm!
To access your Sympatico's web site via FTP through your browser, try entering the following URL: ftp://userid:email@example.com
And thanks to Lianna for providing this information!
