My wife wants to learn how to play poker

[NL__Fool]

Whats the best thing for her to start on? Should she start playing limit, NL or Sit N Go's?

I've started her off over the last week playing short stacked NL for a 20 BB buy in, but since short stacking isn't my strong point I don't know if thats the best idea.

The reason I started her off that way was it introduced her into basic concepts like starting hands and position without having to get involved with pot odds, implied odds, fold equity etc over 3 streets of play.

Whats the easiest thing for her to start on?
