hie guys, i recently installed and loved this software,however i would like to know how i can remove the powered by codologic link if its permitted.thanks

You need to purchase any of the paid versions to remove the "powered by" link.

This may sound silly but how to do get the paid version of FreiChat? I do not see a buy button for it on the main page nor do I see one in the administrator control panel for FreiChat.

You can buy it from here: http://codologic.com/page/codo_commerce/buy
