Dear webmaster

My classmates and I research about OSS repository(especially Gnome) . We have one main question about developers of Gnome.

What way was selected OSS developer?

Do software developers are given the time frame specified?  

How developers list in a given time can be achieved?

    

Thanks for your Help.
