Since folks randomly have problems finding this information, and it has changed a bit in the last several months.

Q: I left the Isle and forgot to train as an artisan. How do I get my recipes?
A: For Qeynos and Freeport, visit your wholesaler society and /hail the NPC behind the counter to gain artsan 2 and receive your first recipes. (If this doesn't work, try the merchant at the bottom of the stairs, and/or the crafting trainer outside the instance.)

For Kelethin folks, hail the Crafting Trainer outside Tunare's Pages.

The crafting trainers located outside the main crafting areas will also certify your level 10 and 20 crafting choices.
