     * The splashscreen is the connection between me and my users, the glue that keep
     * together our invisible relationship.
     * Now it is up to you to decide: you can block the splashscreen forever or not,
     * reject a message that brings a little of happiness into your day, spent analyzing data.
     * Please don't do it.
