PB Wki and Zoho Wiki
I learned alot from the videos on PB Wiki. They gave good examples of the benefits of using wikis for collaborating on projects. I preferred Zoho to PB Wiki and I created my own Zoho wiki homepage. Zoho also other products including templates for writing speeches, student progress reports, online spreadsheets, all kinds of things that could be particularly useful. And, I saw an awesome slideshow on ZohoPhoto:http://show.zoho.com/public/costalsina/Fotos2007.pps. Which I added to my del.icio.us.
