I plan on playing with a bunch of the code on the site (I'm an FPGA newbie). I noticed that the pong.v and hvsync_generator.v files have only a couple comments within the code. The required frequency for the 'clk' input signal is not mentioned (which is critical for the VGA video signal to work). Maybe try to encourage well-commented code for anything that will be posted. I plan on making contributions in the future.
Looks like a good site.
Thanks...
