Teaching kids that it’s better to give than receive on their birthday sounds about as fun as breaking the news that Santa doesn’t exist. Echoage makes the lesson easy. The online party planning service shows youngsters how to value social responsibility and environmental awareness while still having a blast. Here’s how: Choose an invitation. Let Junior pick a cause. E-mail the invites to your guests. An R.S.V.P. tracker tallies responses and contributions (instead of presents). Once everyone’s ponied up, you split the amount and buy one special gift requested by the honoree and donate the rest. Keep up the good work by sending paperless thank-yous. Your little darling’s ultimate reward: a permanent spot on the nice list. Available online at echoage.com.
