We do online signups for our youth events. I'd like to do only online. (no more "sign up sheets!") So, I have a computer that we can use where our youth meet (plugged in via network cable to our DSL connection). Is there a way to limit that computer so that it can only go to our church's website? That's where the signups are, and there is no reason at all for that computer to do anything else. It's running IE 7 or 8. Thanks guys!
