Ques From CS Grad Student

[suenacita1]

Hi. I'm a masters student at the George Washington University 
currently taking an Open Source Software Development course. One of 
our assignments was to do a presentation on an open source project 
and i chose Python. I have most of my presentation done but had a 
couple questions where I want the help of the Python community to 
help me answer. 

1. How many members are involved directly, and how many peripherally?
2. What do you use to drive releases?
3. How often does the project release major and minor revisions?
4. What tools do they use to manage the source?
5. How does the Python project resolve conflicts between members?

I'd greatly appreciate some feedback.  Thanks in advance.
