I just released some really cool features on Presbot.com based on feedback that I've received from early adopters. These include:
Chat Transcripts: You can now view transcripts for all the questions asked to your bot. These are broken down into handled vs unhandled (i.e. provided with a default response or wiki search results)
Chart for Daily Views and Questions: As soon as you login you'll be greeted with a new chart that shows your daily views count and # questions asked.
