Reputation.
On TTG every person has there own reputation.
As of right now you have 0 Reputation Points and 0 Reputation Power.
If a fellow member of the site reps you, you receive Reputation points which leads to Reputation power. It takes 100 Reputation points to get 1 Reputation power.
Say I rep you, it would be +50, meaning you need 50 more reputation points to receive 1 Reputation power. You can also receive 1 Reputation power from making 25 posts.
That's all you need to know really about reputation.
