In the Tickets, tool, we have added the ability to ONLY send alerts about ticket changes to the assigned user, the reporter, and possibly an exclusive list of recipients that you choose.  Since this is the single most requested feature for Assembla tickets, and people have been complaining about it, I'll interrupt this blog to provide a quick introduction.

You can go to the Tickets settings panel and, under "notification strategy", you can select "Email ticket changes only to the assigned user and the notification list." The reporter is automatically added to the notification list when the ticket is created, so the default behavior is to notify the reporter and the assignee. When this option is selected, you will have a new "Notification list" panel on the ticket.

Remember to set your email alerts to get only the volume you want.  When you get an email alert, you will see a link at the bottom that says "Click here to change or remove your alert settings", and links to the Alert settings panel.
