About.com was not a good example Don, it was just the first one that came to mind. My suggestion is limited to external sites, where including content inline would be difficult at best. I know that we do not need (and shouldn't use) frames locally, but we need to have some way of "hanging around" while our students absorb external content so we can share and collect info from them. Frames would just be one way of doing it. Other ideas?
