In one day you see your influence number increased by one and the very next day you see it becomes minus one if you contribute with less replies, answers, and did not ask a question.
I would like to know how to control this fluctuation on influence number? Saving Changes...
Interesting question, I have try to make sense of it for sometimes. I understand it a calculation base on your involvement compare to others involvement. Andrew description is likely the best I have seen.
So to increase your Influence participate in Discussion, Comments, Contribute to the Wiki and template, make a Blog, etc. Saving Changes...
