It is no good just posting a link to a thread that appears to have already been answered. If you have a specific still unanswered question then post it here. However as I have said twice before you really should work through some tutorials to get the basics rather than asking such questions here. Once you have done that the answers will mostly become obvious to you. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
