Hi Nkansah, thanks for the message. We achieve that through the CentralNotice feature available for Meta administrators <http://meta.wikimedia.org/wiki/CentralNotice>. You can read all about this notice system, and also see the currently running campaigns at <http://meta.wikimedia.org/wiki/Special:CentralNotice> (marked with a green background).
Setting up a CentralNotice campaign does not require too much work once you learn a bit about the software behind it. Unfortunately for the planning Wikimedia chapter for Ghana (but probably more fortunately for the readers of Wikipedia), the usage of CentralNotice is rather limited, only to important notices for the readers of the projects or for the community itself. The usage guidelines for CentralNotice are available at <http://meta.wikimedia.org/wiki/CentralNotice/Usage_guidelines>. Hope that helps!
