Hey miirage,
You get points for posting, and for people posting in your threads, and you can win points by betting or if someone special donates them. You can use your points to bet in the betting zone, and to buy things from the "petz/store" list (change the colour of your user name, change your cutom title, change someone elses custom title) or if you are feeling generous donate your points to someone else.
I hope that helps
