In review of how to do everything involving P.O.
1) Go to
http://www.pokemon-online.eu/ and download the app
2) Click team builder when you get to the main menu and build your team or import your shoddy teams from text (I know, nice feature). Note that IVs and shinyness can be changed by going to advanced under the sprite and choosing side.
3) On your trainer screen, MAKE SURE YOU HAVE A UNIQUE TRAINER NAME! That is your ID when you log into a server. You can also add an about me/winning/loosing message like you could in the battle tower in DPPtHGSS (only a lot less limited)
4) Save, then close team builder, then go online from the main menu
5) Connect to the beta server.
If you see a password box, change your user ID! Otherwise, go to register and enter a password.
6) Find battle is in the bottom of the screen.
