How does the Point System work in MPMU

Hello,

I am new and wondering how the point system works. I did a search but don't see any topics in the headlines.

I have 15 points, and if someone helps me out, I tip them out of my 15 points??? I see the little button that says give points, but some of these folks have thousands of points, and I have 15. What should I give?

I don't want to offend someone with tossing over a point or two, but I don't know if I need the points for anything else, so I don't want to give them all away either. Very awkward... lol

Is there some sort of guideline? Also, how do I earn points if I am new and don't know enough YET to teach anyone else... Does the points only come from other members when you help someone else.

Thanks in advance for any replies...
