What is a list of legitimate work from home?

There aren't any.

Okay, that's a little too pessimistic. There arelegitimate work-from-home jobs, but nearly all of them involve you doing something you already know how to do, or can learn how to do on your own, and you'll be starting your own business as opposed to working as someone else's employee. Again, there are exceptions... I did some work once for a guy who needed (I swear I am not making this up) "tassels" made from nylon string knotted into a loop with the ends then frayed out (his business involved companies hiring him to send little cards and gifts to their clients, and these tassels were used to make the cards look "fancier"). However, these sorts of jobs are few and far between.

Any "work from home opportunity" where there is a net up front cash flow from you to the company offering the "opportunity" (for "training," or supplies, or equipment) is almost certainly a scam.
