Just experimenting with trial version and it appears that the only ftp available is unsecure. In this case user and password are passed over the net in the clear. Have I missed a setting that enables secure ftp or is this ability an option under consideration for a future version?
I have never thought of this type of implementation; cannot you use a simple FTP connection for your site? The FTP publish has been made in order to permit people to have a simple app for uploading files; you can use your preferred software if you want.
