Notifications allow you to receive email alerts to a particular topic or board when someone makes a new topic or replies to one of your topics you have set to send you a notice to turn them on click the tab that says notify at the top or bottom of any topic. to turn them off click unnotify. To view everything you have set go to your profile and along the left side click notifications and you can see a list of those topics and or boards plus make adjustments to it.
Hope that helped.
Yep thanks. I know that if I'm logged in on my cell(android), and also logged in on Internet Explorer, IE won't show that there's ever any "unread messages since your last visit". Google Chrome will show them no problem on the laptop, while logged on with my cell at the same time. Maybe the same goes for the notifications?
