I uploaded a simple logging plugin that listens for server error messages and sends an email when an error messages is received. I only added this file so you could see how to implement a custom logger. I will be modifying the code and adding additional modules before this is v1. Be aware that this will send 1 email for each error received, so if something raises 10 error messages, 10 emails will be sent out.
Before this is a v1 release I will be modifying the project significantly. I'm planning to have the logger not only email capabilities but also have the ability to send an SMS message when an error occurs. I'm also looking into what it would take to use Live Messenger's APIs and send out IMs from the logger.
