Boxnet, Cool Text, Mind Tools, Voice Thread, Pageflakes, Teacher Tube, Picassa Web albums.
They are all very interesting & easy to use, I just need time to practice.
Boxnet has solved my problem with the senior wiki because I can now upload more documents.
I think wikis are a great idea for digital portfolios because most of the student work is stored offline.
I am also pretty good at uploading audio, video and other widgets.
