contributing to GDC development

[arnuld]

I am primarily a C developer and have 3 years of industrial 
experience in it, mostly have written sockets API related stuff 
along with application development. Have worked in C++ too but 
that is more of personal interest than industrial work. Got 
interested in D language recently. I will be very happy if I can 
do some compiler development work as I have some fascination for 
system programming.

How can I help in development of GDC as a programmer ?
