You get points for every comment, every rating. The more points you have, the higher you climb in the karma pyramid. At some point you will have reached Gold, later Titanium or even Diamond status. The only question is: How many points does it take to achieve this? And where can I see how many points I have? Can I do something with these points at some point? Exchange them for Cumulus points? Please make Migipedia more informative on these points. The page with the karma pyramid leaves a lot of questions unanswered...
