Here is a short, pretty good introduction to
using the vi editor.
It covers enough to get you through this course.
The WS_FTP LE program is available from this site
http://www.ipswitch.com/
Once there, click on the
'Downloads' tab and select the 'Evaluation Software' choice.
Down towards the bottom of the page that appears is a
section on WS_FTP LE and a link to
download it from FTPplanet.com
Since you are using this for school, it should be fine for you to use it.
If you use it a lot for other things, you might want the Pro version (which
costs money) but you don't need that for this class.
Again, at the bottom of the page is a line to 'Download WS_FTP LE.'
Click here and go to the form to fill out to get a copy.
You should use DeVry as the name of the school and you are a member of
of a degree granting institution so you can (and must) click on the last box.
I believe what you get is an email that contains a link to
download the software.
Just follow the instructions and you should be ready to go.
