Staff-run story arcs and sagas can be found here. They tend to have larger rewards than open-ended quests, but the difficulty and quality requirements are high enough to make it a tradeoff.

Quests sent directly to trainer's Pokedexes can be seen here. This includes both private and official requests, not to mention the oft-shadier direct requests.

Individuals and organizations from many walks of life place bounties on the heads of various foes, from police-offered bounties on wanted criminals, to private requests and even inter-corporation wars. The life of a bounty hunter is immensely rewarding, but beware - the better you are, the more likely a bounty will eventually be placed on your own head.

Here, you can enter and edit information about your character, which will be seen whenever you make a trade via Pokedex. If you do not post here, any trades or requests you make will have your trainer name attached to them - here, you can change the name. For example, you could give yourself a codename, or add in information on your trainer's age, sex, and likes that you don't mind showing to anyone you meet via trade/quest.
