What are Points and FRIH$ for?

Sorry if this has already been answered but I didn't find a sticky post anywhere...
What are Points and FRIH$ for?
Can you buy stuff with it or just give it to other members?
I see that you can sell/buy sigs or something with Points, but I make my sigs myself so... Confused

nvm, found the answer in the FAQ on the main site Embarassed

Edit: I do have another question.. how can your points total get negative?

I believe that if you don't post for a while, your points will go down (your FRIH$ will stay the same though).

xiao...two topics about the same thing?!?! Evil or Very Mad
