Version 0.67 and that startup message

["Rory D. Hudson" <rory zumiez com>]

Hello there fellow gnumeric users....

I have a quick question for you, I have the 0.67 version of Gnumeric and
have been using it quite effectively for quite some time, each time I
open up the program I receive a message that says something to the
effect to look to download a new version of Gnumeric...I really need to
be able to turn this message off, whereabouts do I go to do that?
Please let me know, thanks
