I've got a real problem, Dave. My college-age son had a party in my house while my younger children and I were on a trip and now I find that my house is a venue in Foursquare called "Party House". I don't want that. At all! How can I delete my house as a Foursquare venue??

Based on your enthusiasm for Foursquare, I have been getting more into it and am connecting with a variety of different people in my community. Generally it's good fun and since I only check in when I am in a public setting, I have no worries about privacy with people I don't know. Except there's this one guy who uses his checkins to advertise his workshops incessantly and it's annoying to get those alerts. I want to unfriend him. But how can I do that in Foursquare?

My son and his friends are really into a iPhone program called Foursquare, and whenever they go somewhere, they "check in" so that they can find each other. Neat idea. Is there some way that I can add my own restaurant to the list of places where people can check in so that they'll see we're popular and perhaps check us out?
