How to get rid of the annoying "Thank  you" message users see after submiting information in the Joomla contact form. This trick supplied by Leo of Joomla sums it up perfectly. It even shows and lets you create a custom thank you form instead of redirecting to the index page. It only takes about 5 minutes to implement also!

• Make a Thank-You page in Static Content. Choose whatever content or title you want to use.
  
  
• Create a link from the main menu  and point it to your Thank-You page or whatever title you have given it. The reason for this is that we want to findout the exact URL of the link to your static content "thank-you" page. Show the link as published, but you can unpublish it later, the Thank you page will still show even if the link to it on the main menu is deleted or unpublished.
  
  
• Imagine that your link has got the id's something like  http://www.yoursite.com/index.php?option=com_content&task=view&id=15&Itemid=44. This means we now know what the URL is so we can modify some little piece of code...It is only very little!
  
  
• Open with a good editor such as Dreamweaver or equivalent the contact.php file, located in components/com_contact

'       '

at the beginning and the end. Do not forget those! Don't forget the

;

 either at the end

If you have SEF enabled and have some nice URL's defined or have something like (example) http://www.yoursite.com/content/view/15/44/ than put that SEF-based URL into the code...
