Thanks, I checked out the website and thought it was pretty cool. I have added the website to my list of links.
Yes, I think I might rearrange the website articles into categories.
I'm currently posting up every new release on my mailing list: http://chess.geniusprophecy.com/mailing-list/
I am not aware of any companies that sell code for chess engines.
Although, there are quite a few open-source chess engines, such as Stockfish and RobboLito. Keep in mind that if you copy parts of these codes, then your own releases must also be non-commercial (and possibly open source too).
Thanks for the compliments.
