It's refreshing to see one good idea generate others. Such is the case with Newton, MA-based lawyer Sharon Sooho, whose sole-practitioner Web site created a virtual community focused on family law. Along with two other colleagues, Sharon helped develop DivorceNet, a nationwide community for people interested in finding representation on divorce matters. A clean design complements a wealth of information - from instructions on how to file for divorce to how to find representation - and makes this a first-rate site. Visitors can subscribe to Ms. Sooho's newsletter, Family Law Advisor (sent out by e-mail), and can view articles (separated by topic) going back to 1995. One glitch: the domain is officially registered to one of Sooho's colleagues, which makes the InterNIC record slightly misleading.
