Just through my brain.
I notice the point on the profile.
How to calculate the point?
Those points show how active and helpful you are on italki community.
I've noticed they give 30 points for each correction you make to a notebook entry,
and 10 points to write a comment. I'm not sure how many points they add for
answering a question :')
I've been a member here for nearly a month (short of two days) and hang around the Notebook and Discussion boards for fun, for a while. I have one friend listed, haven't taken any classes or written any notebook entries myself, nor started any discussions. Before answering this entry I had 2950 points.
Edited: Now I have 2960 points, by answering your question, so my little experiment shows it's 10 points per answer, it would seem. The quality of the answer is not measured, however. ;-)
