Hi,
I’ve recently got 7 problems accepted in the August long challenge. However, my long rating is … still NA? Can someone explain whats going on？
It’s not yet updated. May be it will take some time to update.

Rating is not actual, see this question http://discuss.codechef.com/questions/20632/august-challenge-ratings
Ratings are calculated using the dynamic ELO based formula (read more about this here).
Recently, in view of the reported cheating cases, after each long contest, the ratings of that month is calculated, together with a re-calculation of previous month’s ratings (with proper action taken for identified cheating cases).
So, it will take a couple of days for the ratings to be completely calculated.
Your ratings have been updated now. 
We see a good jump. Cheers!
