Jesse makes a good point. I wouldn't give out the ftp address to the teachers. There is
a software program called Contribute that allows individuals to update their pages
without disrupting the whole site. However the teacher would probably have to use it on
a computer at the school.
You can easily create an html or xhtml page and e-mail it to the IT person. It only takes
a second to upload it but just remember that you have to include picture files if you
want them to show up and include any downloadable files as well. If you need a free
program to use, try using NVU. Click on the link.
