Your total WikiAnswers contribution points are calculated as the sum of all of the contribution points you have earned. These include first answers, edits, organizational actions, questions asked, and community contributions. All of these points come under the heading of "Contributions" in your WikiAnswers profile. Trust points are slightly different. Contributors do not directly earn these points through their contributions; they are awarded trust points by other WikiAnswers users. Therefore, trust points are not counted as contributions, and do not add to the contribution points total in a WikiAnswers profile.
Trust points do not entirely help you get hired to work for WikiAnswers, since actually getting paid to work for WikiAnswers is different from the amount of trust points you received online.
You get organization points for editing, answering and flagging

Historical contribution points were introduced on Mon Feb 01, 2010, when the Split Contributions feature went live on WikiAnswers.
There is no limit as to how many trust points a person can earn on WikiAnswers. Currently, the highest number of trust points held by a person on this site is well over 8,000.
You can't "level up" on WikiAnswers. You can acquire "Trust Points" when another user gives them to you.
Any action you perform on WikiAnswers will generate a contribution of some kind. Whether the activity generates one or more points depends on the activity. Chatting, forum entries, and merging may not generate actual points, and the totals of your points could be adjusted by future guidelines. The point of wikianswers is not simply to generate points, although the points indicate your comparative interest and aid to the site.
Currently, the WikiAnswers system of trust points hasn't changed - you can only add trust points, and you can only recommend from a question the user has answered by going to the contributors tab and clicking "recommend".
What Are Trust Points?When a fellow contributor or Supervisor recommends you, you receive a trust point. Trust points are points you can gain on WikiAnswers, to show that you are a trustworthy member of WikiAnswers, that your contributions are worthwhile, and very well done. Taken from the Help Center:Trust Points enable you to vote for a WikiAnswers member whose contributions you think are worthwhile and legitimate.It is important to note that Trust Points are not a good measurement of how much you can trust the answer to a question. They are simply an indication of how trusted the last contributor is as a member of the WikiAnswers community.All answers should be critically considered. For reliable advice of any sort you need to consult a qualified professional in your local area. Please see our Terms Of Use for more details.Trust Points do not account for any special rewards, or deals; however, the more you have, the more respected you are in the eyes of others, and, the better your work is. Currently, as mentioned in the Help Center, there is no facility to subtract Trust Points, as this would only complicate matters further.For more details on Trust Points, see the Related link.
