Depends on the person I guess. If they have had two lessons, their instructor should have covered all of the safety aspects and they should be able to fly the kite to an adequate level. So by that stage they should be trying to get up and ride and imo you should be fine to give em some pointers. They might progress faster with an instructor, but if you feel they are safe (for a noob) then go for it.
However, I reckon its a definite no if they have not had a lesson.
My gf has just had two lessons and I am prepared to lend her my kite because I have watched her lessons. I will be keeping an eye on her and trying to give advice without getting in trouble
