While looking into your biographies so far I am disapointed. Yep, dissapointed. So many biographies simply missing while others more or less written down in a minute or two. How do you think mentors will trust you to invite on their project? They don't know you in person, all they know is your biography. So, it is VERY important that you spend much more time writing a really good bio about yourself, your experiences so far, etc. Specially if you have not a Smalltalk experience yet. See for instance an example of a good bio: http://gsoc2013.esug.org/gisela-decuzzi/biography
Now, pick up a pencil and go writing!
