I know I talked to you about being able to set this up for you but upon further thought it is very complicated, for both you using it and me creating it. I don't think it is a viable easy-to-use long term solution. Basically, you'd be using text files or, to make it much better, a custom MySQL database to store your daily messages for which an entire interface would have to be designed. This would be very time consuming. I couldn't do it for less than $100.
I am considering how to implement this into the scheduler as I agree it would be a very cool feature.
