A Karma System?
 

Hey* I hope I am In the right section :S

Please forgive me If I am not*

I am looking for a plugin or anything that will do this for me*

I used to be active on a forum for a game I play* and It had a karma system.

Each time you would give karma to someone that person would
1: Get a little bit more respect from people because they know he has done good things*

But also for each karma you get you will "unlock" a new benefit.

Like for 31 Karma* you would be allowed a picture In your signature

for 41 karma* you would be allowed to give away 1 karma every 24 hours
for 51 karma* you where allowed 2 pictures In your signauture* and allow Gifs* and so on.

Where can I get something like this?

Thanks*
Jason
