I bought my first chirp recently and downloaded the necessary apps to program it on my Xperia Z3. Since I'm a newbie at this stuff, I'm not clear on what all these settings mean in the Plugin Sampler. I see PIN, which I assume is the password to get into the Chirp, Latitude and Longitude (I have to enter these? It doesn't do it automatically?), and Hintstring (What kind of hints can I give here?). Can someone explain how exactly I would go about using this thing? How would someone be able to find it once I've hidden it? Do I have to enter information about it somewhere? I bought it because I thought it could be fun to hide and have someone find it, but now I realize I've gotten myself into something that's a bit over my head. Please help.
