How to redirect new users

I want to add users to my site. When they first login they just see their dashboard. That does not seem very helpful. I want to direct them to certain information. It would be nice if on their dashboard I could have a message like please see our latest post or please visit this page. If that is not possible it would be nice to have then redirected to a certain page after login rather than the dashboard. I cannot figure out how to do this.
