Any edit you make to a question on WikiAnswers goes into the history. You can make a contribution by answering a question, editing an answer, or flagging or unflagging an answer. You can also get in the history by discussing a question or changing its categories. If your asking about the historical count on the contributions list, then the answer is you can no longer add any contributions to this count, any contributions that may already be included will be from the old system of counting contributions.
