Though I 'm no longer new citizen for the cove but there are certian things that i feel confusing to me. Like Power rep etc etc.
Can I read these kinda things somewhere in cove?

As starters, see these discussion threads:

For more background on Karma and Reputation Power, also see these discussion threads:

NOTE: When you 'Thank' someone for a post with the Thank You button on the post, that adds to the person's 'Reputation (aka 'Karma').
