Let me point another mistake which appeared in connection with sorting records in the Humorous Contests of the cite. As we have such Contests as Humorous News and Humorous Advices I think there is no necessity to classify records in those Contests into Humorous/Serious. All records are Humorous there.
Thank's Sveta. Initially it was like that. Experiments showed however that sometimes people wish to publish interesting serious ideas in these contests, so we decided to make "Humorous" a default value and provide "Serious" as an option.
