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.
You get 2 contribution points for asking and categorizing a question.
You get one contribution point for answering a question, as it is only one action.
You do not have to answer a certain amount of questions to upgrade your ranking on WikiAnswers. Any type of contribution will work to get you to the next rank. (Contribution types: messaging, editing, answering, or removing an answer, splitting and adding alternates, asking a question, and editing categories can get you contribution points. See the question "What are the various contributor levels on WikiAnswers" to see the next level you will become.
When re-categorizing a question 1 category equals 1 contribution point.
Asking a question is one contribution point. Each category it goes in is also one contribution point. 1 question (1 point) + 1 category (1 point) = 2 contribution points for asking a question and placing it into one category. Since the maximum number of categories a question can be placed into is 3, the maximum number of contribution points a user receives for asking any new question is 4 points: 1 question (1 point) + 3 categories (1 point for each category x 3 categories) = 4 contribution points for asking a question and correctly placing it into 3 categories.
There are various users with 0 contribution points, so this question is not possible to answer.
Message Boards and Question Discussions both count as community contribution points on WikiAnswers.
Historical contribution points were introduced on Mon Feb 01, 2010, when the Split Contributions feature went live on WikiAnswers.
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.
You get 2 points. One for asking the question. Another for putting it into a category, it counts any number of categories you put it in as one point.
No, recommending a question or a user does not give you contribution points.
Yes, you get one contribution point per answer.
