I'm proud to announce the launch of the Ethereum Alarm Clock service.http://www.ethereum-alarm-clock.com/
The Alarm service facilitates scheduling contract function calls for a specified block number in the future. The current release should be considered alpha software.
* Schedule contract function calls to be executed at a specified block in the future.
* Trustless. No administrative API's or special access granted to anyone, including myself.
* Published verifiable source code.
* Lots of documentation with examples.
I'm very interested to hear people's feedback. Feel free to send me a message at pipermerriam on gitter.
