PingMe - What *Should* You Be Doing?. From the blurb on their website: PingMe takes a unique approach to keeping track of things you need to do - it's mobile and interactive. Just create a Ping, set a date and you'll receive a reminder by E-mail or TXT to your phone. Not a good time? Pings are interactive! Just reply to the message to reschedule for a later date or time. You can even create new Pings on-the-fly from your mobile device, or tag your Pings to create contextual to-do lists.
Pings are also social! Our new contacts system allows you to share, send and receive pings with other users. Coordinate tasks and collaborate with friends, family, and colleagues while staying flexible and in-touch.
