Yurikomi:

Thank you! Do you know how is it counted? For example how many recomendations or reviews you have to do to earn a point?

I don't know about that, but I think it's one point for each. They haven't mentioned it in the FAQ.

Hello.......

I had my points 0 before, but today it suddenly showed -1. Why??

That 'point' and contribution point are both different I guess...
