Brief: I need a web page that will let me enter items on a schedule which will then release those items as messages to our messaging server.
Infrastructure: The website this will be hosted on will be Drupal 7, though I am happy if it ends up being a PHP script which can then be added to Drupal. Our messaging server is Openfire 3.7.1, and we will want these messages to be sent to specific conferences (rooms) on our server.
Example: I will be able to go to our Drupal site, and add the following timers;
Every Weekday at 8:00am send a message to the conference ABC with the content of "Time to wake up"
This Friday at 11:59pm send a message to the conference XYZ with the content of "Don't feed gremlins after midnight"
These messages will then trigger at whatever date and time is specified, and the messages will be sent to the conference rooms.
Further work can result from this project, specifically automating some of these features, or creating auto-subscriptions to groups.
