In my experience, any "system" you set up in order to communicate with your guides should work fine. They're not picky. "Signs" works, and is a great starting point, but I'd encourage you to "simplify" things as you get the hang of it. Ultimately it's nicest (and most convenient) if you can just talk to them. That too will be different for everyone, but it will come in time as you get comfortable with your connection to them. And remember - you can change the "method" any time you want, even temporarily. They don't care about that. They care about you.
