Yes, for me it is SFTP and thanks for your suggestion. I had also considered this and typically use winscp for exactly that reason.
Whilst I welcome the introduction of the FTP feature we will need to push on with extending my mail/ftp watxher service that drops files of ready for EM to translate.
This way I can fill the immediate need including SFTP as well as logging all inbound documents in a generic and travable manner which we need to do for auditing purposes. I had already finished the mail component before 3.6 had been released and now have the framework for SFTP and web services will be next.
Having said that, I like the simple interface that EM provides and I hope the rest of the community gets behind it.
