Hi.
As far as saying anything about my internship, I understand.
Regarding goalball, there really isn't a site to watch our progress, but you can go to this site (http://www.blindsports.org) to learn more about the organization I participate in. There are typically six to eight players on a team, although, as you said, only three people play at a time. Actually, if you do a youtube search for goalball, you'll probably be able to find some games.
Take care, and if you have any more questions, feel free to ask.
