I'm curious is there a way in javascript/jquery or php to check if a message/post is read/unread by the user; or has the message box site changed ?
I'm thinking about implementing notifications system similar to facebook one - so that any new post/message will add to the title a number '(1)'.
My problem is how to determine that user has new unread message, or eventually how to check if something has changed in the message box site ?
