Previously, email notification was a (dreadful) hack because it wasn't supported in XenForo. The XenForo 1.2 release (a couple of weeks ago) added this capability -- but it was incompatible with the old email notification, so that has been removed.Did email notification from the forums get turned off? I used to get notifications for all the forums and I haven't received a peep in quite a while.
WAD - you will only be notified once if there are multiple new messages that you have not read in a watched thread. When you read them, you'll get another notification if any new messages are posted. (This is the same way that notifications worked previously.)I only get notifications for new messages in old threads sporadically: only 3 since 2013-09-07 04:00 EDT (last Wed.). I thought there was no activity!
