Hi ps, so far as I know, I was the only one who added to Fizzer's code and created CLOT tourneys.
I ran 2 of them successfully, and put my code on github where anyone can download it, run it, modify it, etc.
I haven't run more tourneys (they are swiss-matching real-time 1v1) since then, because I asked on this forum 'who's interested?' and didn't get many replies.
If you or anyone wants to use my code, or extend my code, etc, and has questions, you're welcome to ask me.
(you could have a look at the comments I put elsewhere on this CLOT forum about my code, as well).
