You can enable either file share (Samba) or FTP to upload your website files...another alternative is to use WinSCP
if you're a Windows user.
On another similar note, we should probably have at least one CMS option to make putting up a simple website brain-dead simple. I like what the guys over at Concrete5
are doing. I'll try and find a day to wrap that up and make it an option in the Marketplace.
Any other CMS that you want to suggest? Volunteers also welcome!
