Actually I joined 123RF since last year NOV, and it still in level 1,   Past 12 Month Credits Total : 247, still need 3 more credit so tat can become level 2. I just wonder if today I have no sale, so tomorrow is it my Past 12 Month Credits Total still 247 or will start all over again start from 0? Thanks

It is based on a rolling 12 months so it will count your credits using the most recent 12 months with earlier months dropping off.
