Dear Cathy
Regarding the use of open source and how its licensing works. i have research how the licensing of open source works, by browsing the web and reading guides and blogs on the matter. it appears that in order to license open source we must follow the FSF`s guidelines, which state that the best way in licensing open source we must use COPYLEFT, which is a general method used for making a program free and modified and extended versions of it must also be free. the distribution terms are found in the GNU general public license and under this terms we must add two elements to our open source. one a copyright notice ( copyright 2011 daniel ledesma ) and two a statement of copying permissions,  the statements of should look like the example below.
