For those of you that have been looking for a way to monitor and/or block your kids internet access, Action Alert might be perfect for you. I do an indepth look at the Free Version so you can see it before you decide.
Overall: I would say get it. It's a solid program, clean easy interface, with some cool features for free. On the other hand, I think that this will only be effective for computers where a single kid is on the computer. Multiple users would still have the same monitoring and blocking.
Stay tuned for the Maximum Protection plan review!
