Every 10 posts you get 1 reputation Your allowed to give up to 5 reps a day. The spread before you can rep someone you have previously repped is 25, meaning you must of repped 25 different people before you can rep the same person again. You can check your reputation comments in your USERCP (settings), up to 25 recent reps will be displayed. For every 15 reps you own, you will effect another persons rep by 1 point. Meaning if you've got 90 reps, if you rep somebody their reputation will change by 6 points. MOD's will have a set reputation that wont change. Mods repping people will be strict so they wont be given out often. We will never abuse power, this is something we care about deeply, this is a community for fans. Currently we're giving 1 mod rep to all new members which will boost your reputation power to 90.
I didn't know how it works either lol because all forums have different rules/works differently. Thanks for the explanation.
