I created a Filter to show the overdue issues for the current user and shared this with the developers group. This worked fine in that every developer was able to use the filter to see their overdue issues. I then thought it would be nice to email this to all the developers prior to our weekly meeting so I setup a subscription for the filter and subscribed the developers group. Instead of each developer receiving their overdue issues, they all received an email with a list of my overdue issues. Had I wanted to send a list of my overdue issues to the group, I would have used my user id in the Filter rather than current user. I guess the work around would be to get each deveop to subscribe individually to the filter and then I assume it would work although I haven't tested this theory.
