Boomerang, the clever service for Gmail that enables you to send messages at specific times and reminds you if you haven’t received a reply to a message you’ve sent, has left beta and developed pricing plans. Boomerang remains free to use for up to 10 messages per month, but personal accounts (for normal Gmail) now cost $4.99 per month and professional accounts (for Google Apps accounts) cost $14.99 per month.follow link
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
