There is one thing in forums that is annoying me when using mail notifications: When I turn on mail notifications and I am in the forum I can see that there is a new post on a watched thread for example. Therefore I do not need another mail. From my point of view that is going to be spam mail and I am deleting them because I have seen the notification already in the forum. I would prefer an user option that can define a delay of a mail notification and do not send me one when I am currently logged in the forum and see the alert. I hope you could understand this explanation.
