You may also import your teams from Shoddy Battle, NetBattle Supremacy and Pokemon Online. The import from text feature is under File -> Import from text, or it's own button in the bottom left of the team tab. Use the other simulator's "Export to text" function, copy the text, paste it into Pokémon Online Import team function, press "Done" and your team will be ready for battle! -PO
Basically just click export a team. Or when you see Importable Copy on some people's RMT's, just paste that on the Import a team.
Hope This Helped :D
