logbot @delete <num>: Delete posts from the log. For example: @logbot @delete 5
logbot @title <string>: Set the title of your log.
logbot @folder <string>: Change the foldername of your log (by default, the roomname of the groupchat is used). Small warning: this changes the URL to your log page.
logbot @style <stylesheet>: Switch to another stylesheet. For example: logbot @style log. Available stylesheets include: timeline (default), float, opentab.
logbot @font <font>: Switch to another font. For example: logbot @font font. Available fonts include: polsku, notcouriersans; or select None to switch back to default serif.
logbot @uptime: To check how long @logbot has been around
@bots: To see who is around :)
