oh ... i don't know i clicked read more and someone had -19 on their post ^^; sorry i'm new here i'm not sure how it all works yet.
(if i say this wrong correct me so i don't explain the rules wrong)
in a round the predator's remove a point and a prey add a point, the same way it worked on the first page, although technically you can fight for whatever side you want as long as you stick to the same side in a round(if you started with -1 keep with -1, and if you started with 1 keep with 1... our in round tf agents rarely work fast enough)
to keep the score we often type our number out and then after posting edit the comment to put the score in, so that if we all comment at the same time we don't mess up the score, we try and say you have to edit the score in before you can score again. we also say that if your comment appears right after another comment of yours the second point does not count, although other then that its not that big of a deal.
... although we don't really enforce the above rules
the rounds go to 20 or -20 after starting a round, and after that there is a 1 hour minimum cooldown before another round, usualy we leave or go to chatting like this during that time
... and the rule that is only sometimes met, when you start a round you don't add you point, so it goes
"starts a round" (the text, not "s when its used)
0 (if you started the round )
<not your scoring point>
<if you changed the point then the current score goes here>
we also have some images of gongs for starting a round, but those are not really required
