Some of yuo have used Glogster. I have my students with accounts and they can make a glog. How do I have them upload text, images and video? I have been saving to my pendrive and all is well. But could the firewall be blocking content from student shared files to glogster? Planned on haveing them wok on this Monday and I'm a little confused now. Please help!

Thanks for the help. Part of the problem was my learning curve. :)
