Not getting any notifications either, since the forum went down. All of my settings are the same in my user profile (I have not changed anything). I believe I received one notification shortly after the forum went back online. There have been plenty of responses to some of the threads I am currently subscribed to.
On a side note, before the forum went down, I was receiving multiple notifications for the same thing. If someone responded in a thread I was subscribed to, I would receive usually two email notifications of the same user post. Also, if someone liked one of my posts, I would be notified of that twice as well. I was actually considering turning off ALL notifications as it was getting quite annoying. Coincidentally, all notifications stopped when the server went on vacation.
Maybe the server meltdown was my fault? I should not have made a wish on that eyelash...
