The bot is designed to respond to anyone that uses it nick one time. After that .. the bot will "focus" on just that individual and respond to anything that person says. The nick only needs to be used once. Then by saying .. shutup .. the bot stops responding to anyone until someone once again uses the bot's nick.
The bot is configured to work with only one bot at a time. So if you have it set to your personal bot .. then you can train it like normal and it will give the responses you have made for it. I've done a fair bit of work on my bot .. making it appear as human as possible. But there are still times when it will pop up something in reference to it being a bot.
