For example I see I have 5 karma points I can use. Does this mean I have five karma points I can give to people - either in a negative way or a positive one? - And if I use those five points, will I just run out and not be able to give any more?
Your karma points are renewed every 24 hours, so if you dish out your 5 today, you'll get another 5 tomorrow

I seem to have a nett amount of around ten positive karma points, so does this mean I can use those to give to people and lose those points on my tally? (Can I give my neg karma points away as well)?
Your 10 points are points that people have given you, you can spend these on actions such as pinning threads. They won't be used up by you giving karma

I don't really see the point of the karma system. Is it something like:- if I give points away, I'll get other points given to me by the system, and not giving any away means I can't get any more?
Green karma can be given to people if you think they made a good post. Red can be given to people who make bad posts. These options are no limited, in fact you can give karma to whoever you wish

If someone can bring me up to date on what the karma system is all about I will try to see if I can participate in a useful way.

* Can I see who exactly gave me the points? No, unless they leave their name in the message

And... How is the system abused (if it is)? What are the obvious problems - if any - associated with the karma points system. The karma system was abused, but this has now been stamped out by the mods, any abuse will most likely result in a ban




I hope that helped :)
