YOu might have, like I did a while back, accidentally mark one of the board emails as spam. If you've done this you have to wait 2 months to receive email notifications again. If Admin opens you up before that it will leave the entire board open to spam. At least I think that's what I was told. You can click on Watched Topics to check on things. It's a real pain for two months but it too will pass. I thought my time would NEVER get over. Contact Admin and find out for sure then mark the date that you can get back on. The day before the date contact Admin again so that you can get back on. If this is what's happened there's nothing Admin can do about it for two months but contact them to make sure.
