hi I m using joomla and I want to make according to my needs? how can I make user controle panel according to my wish? is it possible?
You can try to use another joomla backend template (the default template is khupri or something), you can search at internet, there's some of them.
if you mean how do you modify the user panel to do things other than what's included in the base cms? start by getting the joomla source code and cracking open a php book. if you want to add new functionality to joomla you need to have a strong mastery of php.
