JavaBot is a chat bot for the AOL Instant Messenger, MSN Messenger, and Yahoo! messenger systems. It is designed to attempt to engage in conversation with people via IM. It supports such features as remote administration and full conversation logging. There is also a mechanism for eavesdropping on conversations other people are having with the bot. All administration is handled over IM, allowing remote administration. Using a simple scripting language, the bot's conversational responses can be modified to taste.
