What's a slug ?!

Your instructions for Mochi game adding says this, under Category:

"You may place the slug of any category in this field to limit the type of games in the feed."

What is a slug? I think maybe that's a mistranslation Sergey ;-)

No, the word is correct and taken from the mochimedia feed's documentation. In short, slug is a name of a category (Action,Puzzles,Shooting,Strategy,Other,Sports,Dress-Up,Adventure,Education,Rhythm,Board Game,Casino,Driving,Fighting - as my category listing utility informs).
