Notifications are simply little messages sent to you when something interesting happens; such as one of your entries being commented on, a friend reaches a milestone or if you receive a note from a moderator.
Generally they should all be positive though!

This feature has not been lost, it is simply a glitch that we are trying to resolve.
Thanks.
That's great! Will remove previous comment :)
when we are setting up our notifications page there is a column asking if we want a 'push' for some of the things. what is a push? i was once on facebook and heard the term there but never understood it.
When I post getting message invalid dimensions- what is that about?
