OOH clever!! Lets hope people use it!! maybe the search function needs to be a button like that, then people might use it instead of posting the same thing over and over again instead of looking for it!!!
Its a button that finds all -new- posts in a forum. So if your in the main SW forum and click on find, it will find all new posts in SW and its sub forums.
Its like the "New Posts" button in the blue banner at the top (First line in the middle), except that button will show you all new posts in all sections of MiniMins.
