Today's technology gives parents many ways to keep track of their kids.

Cellular carriers let parents control when kids can use their phones and who they can call. GPS devices let parents see where their kids go and warn them when young drivers break traffic laws.

Programs for home computers, meanwhile, let parents see every Web site their kids visit and every message they send online.

For an upcoming story, we'd love to hear from parents who are using or have used these sorts of tools.

We want to know how easy (or hard) they are to use, how well they work and (most importantly) how much they helped your kids make wise decisions.
