Earning points
Participate in your community to earn points. These points are what you need to advance to higher levels.
Basically, you can earn points by taking certain actions in your community, such as liking a blog post, creating a document, or writing a status update. You can complete missions as a fun way of earning points. Depending on how your community is set up, certain missions might even be designed to help you earn points instead of badges.
Current points and lifetime points
Current points usually refers to an immediate, spendable balance.
On the other hand, lifetime points refers to many points a user has earned in their lifetime. The lifetime points number never decreases and is an indicator of status and seniority in a community. This is also often used as a basis for Levels, as described in Leveling up. Lifetime points determine how much more points the next level requires.
