File Transfer Protocol (FTP) – Transfers files between two machines
Requires an FTP server on the host machine and an FTP client on user’s machine
Much like the webserver/webbrowser relationship (“client-server”)
Requests and replies for files instead of HTML documents and components
FTP: manual ftp
Login to host machine
ftp sole.stanford.edu
username: bob
password: ******
To request a file(s)
get program1.cc
get *.html
To send file(s)
put program2.cc
put *.html
FTP: Getting Graphical
Many, many free graphical FTP programs are available
Two recommendations are:
WS_FTP LE
CuteFTP
Both are available at:
http://www.tucows.com
FTP: GUI Login

Instant Messaging (some flavors)
Email lists
Delayed Collaboration Examples
www.dejanews.com
newsgroups on various topics
gsc@drizzle.stanford.edu
mailing list of all Stanford graduate students
www.stepfamily.net
email questions with public replies
ask the experts
like “Dear Abby” or NPR’s Car Talk
http://www.delphi.com/extremecompute/start/
specific topic message boards, hardware

“walk-around”, explore, build, interact
Virtual Worlds
Ultima Online
EverQuest
Asheron’s Call “games”
Hitchhiker’s Guide to Earth
building knowledge, collaboratively
