Question about SVN

I have read Get Involved page, and I have some questions:
1. How can I access to SVN, I mean where or who can I contact to get user name and password?
2. I want contribute as a developer, but in SVN_Guidelines page, we have about 3 involved in coding. so how we choose developers in contributors?
3. Can Tester change code?
4. Ticket page is bug manager page, isn't it? so, do we have a "idea manager page"
?
ps: I'm a IT student, and I involved in coding so that I can have experience about software development.
sorry for my english!
