Categories and subcategories


I was wondering of someone could tell me the best category and subcategory for a gig I am trying to post? The title of the gig is “I will teach you 5 red flags to identify e-mail scams” I have tried the following categories; On Line Marketing, Programming and Tech, Business, Life Style, and Other. Each time it says it’s the wrong category. I am about ready to forget about it and move on. Does anyone have any suggestions? It would be greatly appreciated. Thank you so much.
