I've been reading over and over the descriptions for options 1 and 4, and I think I understand what option 4 means and I have it enabled.
However the description for option 1 "Remote login" simply does not make any sense: '"Remote Login" can be disabled. Useful if you're hosting totally separate websites.'
I have been programming for 15 years and I can talk HTTP directly via telnet with a server, but I just don't get this. Please explain what the option does.
