The Hushed Casket was founded in 2002 shortly after the launch of the XBOX console. Today the Hushed Casket is a thriving community of gamers, playing together and publishing news and stories that have appeared in major media properties like Newsweek, G4TV, USA Today, and Penny Arcade. Some game developers have even referenced our guides and news to support their gamers. We don't play Halo. We LAN Halo.

Get notified of game nights and important THX announcements via the hushedcasket Twitter account. You can get the messages on your cell phone, through email, Facebook, and many other ways. Here's how it goes down.
Remember the Milk + Twitter
Remember the Milk + Twitter = Win
I stopped using RTM over a year ago because I started using BaseCamp.
However, I really like RTM's integration with Twitter. Like you said, you can just send a short SMS to RTM's Twitter account and it'll be smart enough to add it to your calendar and then send you an SMS alert when the appt is about to take place.
I'm going to start using RTM more often. It'll be great for setting up lunches and other events.
