hubot-irc adapter v0.2.2 includes a patch adding a sendPrivate method.
Adds the tested change mentioned in the pull request. Sends user a private message when they ask Hubot for help.
To solve the problem at the meeting of people flooding the channel with 'what did i miss' commands. Replaced send with sendPrivate everywhere the ineffective direct_user helper gets used.
Merge pull request #1 from jiko/sendprivate

sendPrivate for long help and logging messages
