I took the advice of one comment in this blog, and explored the use of Plone, an open source content management system. I downloaded the Macintosh version to my laptop, but have not tried it there yet. My ISP does not support the Zope server, so I could not load it on my electronicportfolios.org server space. However, I found a free Zope/Plone server in Europe that allows 10 MB of online space for non-commercial use. I uploaded my portfolio documents to this site. Now, I am trying to figure out how to make it visible without a password.
It is a relatively easy system to learn, although it doesn't convert URLs in the text to links (I had to upload HTML code from documents that I had created in Mozilla). I was impressed that it automatically created a web page with links to documents that were stored in folder. I can see real possibilities for using this system for portfolio development.
I also used a customized system, the Personal Learning Plan developed by David Gibson through the Vermont Institutes. The program is designed to be used with a set of standards, rubrics to evaluate the documents, and feedback from an advisor. When I published my portfolio, the system automatically added those extra blank sections at the bottom of each page. The program was relatively easy to use, but I only used a small part of what it was designed to do.
