This option will replace the normal “Dear %nick%” in the bot reply with your custom message. The use of token is also allowed. However, you need to use at least a header that will be unique for each user, this allows the server to treat messages differently and the bot gets banned for spamming much less often. For example, beside %nick% which is unique you could have “The local time is %time%, here are the results of your query”. An example of a token which doesn't produce unique result every time is %topfile%
