Your rep is dropping because people have negative repped you. Probably because they disapprove of some of your posts. Click the user cp tab and scroll to the bottom of the page and you will see the posts that caused this negative rep. Only jrvip and above members are allowed to -rep someone. You should try to make helpful and intelligent posts and maybe you will get your rep built back up. Not saying you don't but obviously some posts have gotten negative views.
