Hey Steve,
do you know when you will be adding this?
First we'll be adding uploading to FTPS (aka SSH FTP) and then we'll be adding the ability to uploading to network shares.
Also I think I've found a bug in the upload your updates, before I found out you couldnt upload to a network server I added a network path as an upload site. I saved everything and then wasnt able to reload the project as it said it had an invaild port. Also before the above when I tried to edit the newly added site it throw and unhandled exception
Can you tell me how you added the site? (What text you entered where?). Also, what type of VPN server are you connecting to?
