Hello there,i have a slight concern here.My friend has been using some commercial joomla components for his websites and encouraged me to try out some of his,then see how well they work.

My concern however here is that maybe those components could have some call back codes,so in the process of trying,they may get me in trouble.Could someone help me here please.

may be. it is better to check the code you will get.
anyway what components you will get?

just one component.something like fill a form by Taylor....
