I would appreciate it if you took the time to read what your about to post. Punctuation and actual sentences are good on forums as it helps people read your posts - They may even be able to understand what it is you're trying to say.
When people like what you post, appareciate what you post, see effort, agree with you - They will rep you and you will to them too. Negative rep is the opposite of that. I don't agree with negative rep.
The more you post, the higher the ranking. That's simple.
Everybody has points and you can use your points to bet on fights, you can enter the lottery for the chance to win more points, you can buy customizations for your username and user title and you can buy people gifts! Like donuts~!!!! It's all very exciting.
