If you think that Facebook is just for teenagers, think again. It’s catching on in the over 40 set. Women@Work recently created a Facebook group—and within a day there were over 100 members. Very impressive women continue to join (respectable graduates of Ivy League schools who have nothing in common with teenagers!), and we encourage you to create a free Facebook profile (www.facebook.com) and join the Women@Work group, too. Leave no networking stone unturned! (Just don’t expect your teenager to “friend” you!)

For all current and returning professional women looking for valuable contacts, LinkedIn is the place to be. It’s an incredibly useful tool that allows you to search for connections to specific people, establish contacts at companies that interest you or simply look for networking ideas among people who have the job title you have or covet. Go to www.linkedin.com to create your free profile and join the Women@Work Network group.

Yahoo has a new web site devoted to women called “Shine”. The editors say it’s not a site just for moms or just for single women or working women, or any specific demo- or psychographic: “We wanted to create a smart, dynamic place for women to gather, get info and to connect with each other and the world around them…[and inspire them] to laugh, think, get mad, empathize, and be surprised and entertained.” Visit http://shine.yahoo.com and zero in on the “Work & Money” tab.
