My friend Cheryl Hepfer appeared on a recent episode of the ABC News program “Nightline” to discuss how marital cheaters are being caught these days: their racy text messages. Like lipstick on a man’s collar in days of yore, text messages are alerting spouses to their loved ones’ infidelity.

Tiger Woods is a good example. His wife Elin Nordegren learned about his cheating when she viewed text messages sent by one of Tiger’s girlfriends. Now the couple is heading for divorce, according to news sources.
