Why it can't be as it is in any other normal forum? To subscribe or unsubscribe to the thread that interests you, and that's it?
In the beginning, when you changed to email notification, I started to get the email for ecah edit at each site I am a member, including this site and its forums, so I started to get tons of emails per hour, which was unacceptable. I tried to unsubscribe from all of them and to subscribe only to those threads I am interested in, but there was no way. Then something strange happened: I couldn't stop emails, even though I thought I unsubscribed from all. Then I had to make a filter in my email so everything from wikidotmailer goes directly to the bin. Then, I saw you put the options to follow page, thread or forum, so I deleted my filter and started to subscribe to some threads where I posted, but then I started again to receive email notification for every and each cnange in Community site and its forum. I unsubscribed, then after some time, I subscribed again, but now I don't receive anything, just a notification if I have new PM and I am not on Wikidot.
Sincerely, I don't have a clue how email notification works at Wikidot, so I just come from time to time to the Community site and check last posts to see if there's some answer to my questions, then have a quick look to all other forums, and that's it.
