Historical contribution points were introduced on Mon Feb 01, 2010, when the Split Contributions feature went live on WikiAnswers.
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.
