I recently tried DigiCation Spotlight, another ePortfolio tool. This was the 21st tool that I have used to re-create my electronic portfolio. The process moved pretty smoothly. All URLs had to be converted to weblinks (it did not happen automatically). The tool allowed me to reconstruct my portfolio in less than an hour, copying the information from various online portfolios.
There is no data management tool, to aggregate assessment data. Therefore, this tool might work for formative assessment (providing teacher and peer feedback on student work) but not for summative assessment. The tool does not allow comments (as in a blog) or collaborative writing (as in a wiki), so its utility is really as a presentation portfolio. At the present time, the tool does not allow exporting the portfolio as a stand-alone archive. The real advantage is the price. At the present time it is free to the first 1000 users in a school.
