I read several forums and every forum, other than the LimeTech forum, sends me an email when there is a new post to a thread that I am following but it doesn't send me any more emails about this thread until I visit the thread.

 

These LimeTech forums send me an email every time there is a post to a thread which can fill up your inbox as you can get a dozen emails in an hour when there is a very active thread.

 

Is there any way to change this setting so that it only sends me one email about a thread until I visit the thread?

These appear to be the options available under account setting/notification setting (which you get to with the drop down on your forum name):

 

Method to use for content I follow automatically

•     A notification when new content is posted
•     One email per day with all new content from that day
•     One email per week with all new content from that week
•     Do not send me notifications
