Chat Controller will allow you to set up rules for when chatting is not allowed. For example, you can create a rule so that your child John cannot chat on MSN Messenger each night from 5:00 PM to 9:00 PM - all while still allowing your child to chat at that time! Chat Controller works with all popular instant messengers, including: AOL Instant Messenger, MSN, Yahoo!, and many more. Chat Controller is secure from unauthorized changes to schedules because it runs as a Windows Service and it can continuously synchronize your computer's clock with the atomic clock to prevent unauthorized changes to your clock. (Changing the computer's time won't defeat Chat Controller!)
