If you have any issues with an email not sending when it should, I recommend that you reset the permissions. I had this issue with this code after a while and I was able to fix it by removing the permissions given and then giving them back again.

Hope this helps anybody that would have the same issue.

Hi, this code it great and I've modded it already to suit my needs. However, I am struggling to change it so that the email sent does not include the body of the announcement. Any help on this would be much appreciated.
