It has taken me more hours to figure out this system than any of the others I tried. The interface is simple, but the version that I tried was somewhat restrictive. It didn't seem to have any way to just add a simple page. I really liked the list of "My Items" which listed every component of the portfolio, categorized by type of entry. However, there does not seem to be a way to categorize the items any other way, unless attached to another item, as I did with Competencies. The program does allow the portfolio to be exported in HTML format, but cannot be viewed publically without an invitation and password. It doesn't appear to have the assessment database in the background. It is an interesting program, but too structured for my taste. Still, I can see how if might be attractive for some institutions. One thing I did notice, when I exported my portfolio to a Zip file, iWebfolio published the HTML portfolio in frames, a violation of sec. 508 disability standards.
Nuventive has an additional program called TracDat, which is an assessment management system. At least the company has kept the two components separate, as I discuss in my "balanced model." I assume the two components talk to each other, but I have not looked at that system.
