Okay, so it's a little confusing, but the gist is when you create a chat room (create chat) your automatic password is the "My ChatCode" up on the top right. When your friend clicks "Join Chat" they will be asked for that code. Let's say the code is 744569, they type that in, and abra kedabrah! You can now send numbers to each other.
I will be adding an encoder to take words, turn them into numbers, and reassemble them back into words on the other computer. This is pretty much just a test right now. Most features are broken. If it says the servers are full, simply click the speech bubble and type /dev wipe. This feature will be removed later with a server auto-closer.
