ok simple explained...
when you install joomla you have an account as admin,you can use that to administer the site,and login in front or backend.
But i had another account as normal user to and recently i added administrator rights to it.
So when creating the list i added the registered users group to it not knowing that it wouldnt recognise my user account anymore cause i wasnt a normal member anymore..
So when i searched for myself in the search box it showed nothing....
