Do you limit the amount of time you allow your kids to spend on the computer or internet? It wasn't an issue up until recently when my kids created facebook accounts http://www.facebook.com/ and began a new game called FarmTown. I notice alot of their friends and even my friends are in farm town. I frequently hear them talking about farm animals that have been sent to them and how cool this or that farm is. It's easy to spend hours on the computer and not even realize how long you have been on it. Just wondering what other parents have setup for guidlines on the computer.
