All my favourite artists are set to notify but I don't get emails for all of them, only for some of them... That's an even worse bug to trace lol  I deleted one off my list and added him again to see if that makes a difference. Also, one artist who is usually very popular thought that he didn't have a big response because of the subject of his picture. But I think people don't get notified, so there are less comments in the galleries...

Thinking about it now that I see the checkbox... I was getting notified for one topic I contributed to in the forum but I never checked it to be notified.
