well i wouldn't complain, even if i never submit anything (i'm not the art type), but i just got into MT, i had gained 0 credit so far, and then i checked my notifs, i had gained 0.5 credits, and then i opened a few pages, and each time i open a page i get 0.5 credit.... well i'll keep on opening pages? ;)
anyway i don't know maybe it's just that i had actually gained a number of credits, and they go up not all at once but regularly? i don't even know if it's a bug ^_^'
EDIT well apparently it stopped, so i guess it's just that it didn't come at once
