Want to know how to share a save file with someone.

[Alejandro]

Just wondering how do I share a save file with another user?

If you look in your standard Pokémon Reborn folder there should be a shortcut to your save folder where you can take the file named "Game.rxdata" (or Game_#.rxdata if you've got more than one file) and copy it to send it wherever you like.
