Hi Chad,

Thank you for your very detailed description about the project Idea.
It Increases my Interest  about this Idea.

First of all I thought the mentor is Jordan Justen (As the Idea page says).
If he is not please tell me how should I get a mentor to this project.

As it says I think I have to work with windows environment (I'm very much
familiar with windows and most of my work done in windows environment) . So
it wont be a bigger challenge to me.

*So first of all I think I should have a mentor. Can you please help me
with that.*

And of course although you are not familiar with programming in a Windows
environment.  If you can guide me through this, to get a basic
understanding about X.org and Waffle and WGL to enter to the project it
will be very much helpful.
Please give me some resources, reading materials , tutorials ... anything.

By the way I don't know without a mentor it is useful or not. But I would
like to give a try.

Thanks and best regards,
