In another system, I had access to cPanel. It included a File Manager that I found very helpful. One could use it to do the obvious file mangement and house-keeping functions, but its main asset was that it was relatively user-friendly. Certainly much more so for a newbie than anything I have been able to find so far on DreamHost.
If anyone is familiar with cPanel, could you tell me if anything like that exist here? You can see what I mean at: http://www.cpanel.net/index.cgi
