I'm new here and just started today (today mind everyone) and I have no idea how to level up my Pokemon, so it's kinda frustrating when there isn't some sort of tutorial or guide around to help.

So, how do I level up my Pokemon and where do I go to do so?

Go onto the option "Your Pokemon" and go onto "Change Moves" and change one of the moves to Bolt Strike. Then go onto NPC Fights and battle Swimmer Richard under the "Intermediate Trainers" category and keep using Bolt Strike. He has a Prinplup that its level is twice as much as your starter Pokemon. (The Pokemon that is in the front of your party.) I hope that I helped.

If you look in the general discussion there are a couple of guides that will really help you get started, they helped me a lot :)

what i did to level up was to change your moves to moves that are super effective to your opponent so really just fight who you good at and fight lots of NPCs the 2nd group of trainers are two times the level as you so change your moves to electric moves so your super effective

They are all on the first page on the general discussions.
