I have set up a google site. The web address is
http://sites.google.com/site/ppcgeeksproject/ If you would like to contribute, that would be very welcomed. We can tie the project into this thread.
Just let me know if you would like access as a contributer by sending me a pm with your email address (is required to send you an invite)
The reason I went with google sites over wiki, is because wiki has a bit of a learning curve. With google sites, anyone that it not familiar with wiki editing, can now also contribute to the project.
I suppose we can give this a trial run. If all goes well, I may just abandon my post altogether, as this will further fulfill my idea of something community driven.
