A Search dropdown box has now been added.
The Search facility has been improved.
Until now the search button only searched the board or topic that you were actually on - but it wasn't clear that that was the case - i.e. most people would probably have wrongly presumed that using the search button would search the whole site by default.
With the dropdown you can now choose which topic to search or, of course, choose 'Entire Forum'.
Well done Admin :)
