What is the goal of the point and level systems
Once you are on a little higher level you can post without delay and message more people. I think it is to cut down on trolls. It's annoying but it's nice to have a place for intelligent discussion without being drowned out by people who only want to disrupt the discourse.
There are lots of ways for you to earn points so your level will increase. Take a look at the "Levels" page at [agnostic.com] for more details. The points/level system is just a way to help us reward active members by giving more access and perks to members as they increase their level.
Don't get too hung up on the points/levels as they are mostly just a way for us to keep scammers away. Thanks for the question! You can read more on the FAQ page (see link at the bottom of every page).
