I'm currently using Silverstripe 2.4.5 with the forum module. My website is made up of different classrooms with a different forum for each classroom. There is a teacher for each different classroom forum. How can I send an email to that teacher when a new topic is added to that forum? The subscribe for thread works fine, I just want to extend that to include new topics but am lost as to where to find that and how to include it. Is it possible? and if so how do I go about doing that. Thanks!
