Guild Wars 2

I noticed it is possible to purchase other discipline recipes, and when you double click to use them, it goes away like you “learned” it. What I’m curious about is:

1. Are all the recipes I have been buying actually being learned even though I dont have that profession?

2. Will they show up on the known list when I do finally pick-up another discipline, or will I have to re-purchase all the recipies again?

(I figured I would buy them anyways as I come across them, “Just in case” :P )

I really hope I’m not wasting karma buying weaponsmith recipes from hearts when I have leatherworking/huntsman :O
